Ok I have just cleaned my 1983 atc 70 carb. Also sealed the gas tank, and put in a new plug with new gas lines. My pull start is broken so the only way of starting it is to push start it. Final: I pushed it in 4th gear and it did not even sound like trying to start.

Do you think when I cleaned the carb and hooked the new gas lines to the carb I put them on backwards. So its not getting gas?

NOTE:When I unscrew my new sparkplug it is as clean as clean and no smell of gas. When I push it in 4th gear with the plug unscrewed by the head of the motor and I get a big blue/purple spark.

I also took the carb back off again and the bowl is filled with gas. The only thing I can figue is I didn't put the throttle back into the grooves of the carb exactly. Is that what it might be???

Here are some pics of the way I hooked up my new gas lines, Please tell me if I hooked them up wrong.

Well i got it going a little with the air cleaner off then it make a poping sound and I have major gas leaks on my new lines and then You know what I mean man did it go Flames hit the tank almost. If I wouldnt of jumped off when I did I would of got burned severe??????

I push started it again today Friday (10-05-07) and The only way to get it to try to run like 15 feet is to spray engine starter in the carb/air cleaner???

What kind of compression do ya have on the motor,1st off ?????

james9r9r

10-05-2007, 10:20 PM

Well what do you mean ???

It seems it has good compression?

Once you get it worked out a few hose clamps may help stop the gas leaks.

Yea I got some now and got good new lines that fit tight but yea man it went up into flames I mean big... But that's a plus + I got it to go for a few 15 feet

But The only time it starts a little is for about 15 feet or less when I spray engine starter into the air cleaner.

Do you think I am not getting gas from my carb into the motor??? or compression points etc???

Put a little gas in the spark plug hole, if it fires then you know it's a fuel problem. If it doesn't, then I'd look for a good solid spark, and if that's good, I'd check timing, and then compression.

10-06-2007, 01:21 AM

hey something is up with the fuel lines or carb. take off the fuel bowl and turn the gas on to see if it flows out, also check your float and jets. and make sure you put the needle back in the carb.

james9r9r

10-06-2007, 01:35 AM

Ok I have had the carb apart and cleaned 3 times now ok?

And you said put the needle back into the carb as in the throttle one or the tiny one in the float???

james9r9r

10-06-2007, 01:40 AM

@ (TwoHundredEx) :
I am getting good spark when I unscrew the new plug and touch it by the head of the motor and I haven't used a tester but I know I have ok compression and Don't you have to have it running to time it. Also might it be the points not set correctly?

Do you think it is a fuel delivery problem?

try puttin a little gas in the spark plug hole then put the plug back in and see if it fires, then come back and let us know if it fired or not

james9r9r

10-06-2007, 02:13 PM

Fired as in tried to start? or started up and ran?

james9r9r

10-06-2007, 02:29 PM

Yes I poured alittle gas in the plug hole and it sounded like it was running very quietly and went for about 6 seconds??? So yes it fired???

Brockey

10-06-2007, 02:44 PM

Well your doing better than me. My 70 floods even with the gas turned off. Think I have pet cock and carb problems.

james9r9r

10-06-2007, 03:10 PM

Brockey I need you to take a picture of your carb and how your gas lines hookup could you please?????

Brockey

No sweat. be back in a few minutes.

Brockey

10-06-2007, 03:46 PM

Alright first off my bike needs to be restored and everthing is a mess. The red between the intake and carb is a chunk of my 250r's rear fender as a gasket.

Ok should that be the same hookup as my 1983 you think???

stoney420

10-06-2007, 05:30 PM

james, if it fired when u put gas in the cylinder then you obviously have a fuel delivery problem, when u took the carb off how much gas was in the bowl? try startin it with the gas cap loose to let air through maybe your cap is clogged, or if it has one of the gacaps that you can turn on and off make sure its in the on position, also put the 2 screws on your carb back to stock setting, im not sure what the settings are but if you dont know them then im sure someone here can tell you..
you said in your last thread that you cleaned the carb out real good right? make sure the jets in there are all clean u should be able to see through them when u hold it up to the light
download a service manual from here.. http://www.drivehq.com/file/ShowFile.aspx?catID=0&subCatID=0&view=&sort=&isInc=&isGallery=true&share=true&shareID=233462&parentID=636956&fileID=31501625&curPage=0&ft=2/24/2007%2012:04:49%20AM this will help u with alot of your questions

10-06-2007, 05:42 PM

hey man i was just comparing your pictures to the ones that brockey posted and u have your hoses on wrong it seems..switch them at the carb, the one thats on top switch to the bottom and the one on bottom switch to the top
im assuming one is for reserve so i think it should still be running the way u have it tho unless u dont have much gas in it?
also in your pics u have your gas off, make sure you turn it on it should be up and down, not side to side...

blue27

10-06-2007, 05:59 PM

Alright.....Fill the tank up all the way and it does not matter were the lines are at the moment, what you need to do is find out if you are getting gas to the carb.

1st Are you getting gas out of the lines? Pull the hoses and see if gas comes out of the tank.

IF NOT then either the tank is clogged onthe fuel cap is in the off position or defective..take the cap off and see if that allows fuel to flow. If youare getting gas from the tank then.....

2nd There is a screw on the BOTTOM of the carb with the gas turned on lossen that screw, gas should flow out of the hose in the bottom of the bowl.

IF NOT you are not getting gas to the carb

Possible issue is on/off switch is clogged (there is a filter in there) or the rubber seal in there is bad.
OR you float needle is stuck or clogged

With the carb off pull the float bowl off and with the float hanging down spray cleaner into the on/off valve assy. to simulate gas flow into the carb. IF NO gas comes out there is your issue.

try that

stoney420

10-06-2007, 06:10 PM

here found you your carb settings too, set your screws at stock setting for now till you get it runnin then you can fine tune it after if need be..

10-06-2007, 06:39 PM

Well yes I am getting gas to the carb...

I also notice theres two metal pipes on the gas tank if you look inside the tank there is one tube and I dont see the other hole I am thinking the other one is clogged so what could I use to push through and try to break through my sealer???

blue27

10-06-2007, 08:46 PM

The tube is for the "ON" position the other hole witout the tube is the "Reserve". Try a Coat hanger to clean it out. Now you need to find out if you are getting gas into the float bowl.

james9r9r

10-06-2007, 08:53 PM

Yes I am getting gas into the float bowl??? Coat hanger is way to hard to get in .

james9r9r

10-06-2007, 09:24 PM

So do you guys think it's a fuel delivery problem cause everytime I pour alittle gas in the plug hole it fires?

ATC-Eric

10-06-2007, 09:29 PM

Yes.............

blue27

10-06-2007, 09:49 PM

If you are getting fuel to the bowl.. then I am going to say its a clogged jet, check both the main and slow jet,and make sure you can see through them or spray cleaner through them,. If any of the jet is clogged it will not run. I use a wire from a wire wheel to get through the slow jet. Make sure the cross holes are clean also in the jets. There is a hole through the center and some cross holes on the jets.

james9r9r

10-06-2007, 09:56 PM

Srry I have some knowledge but not this.

Well how many jets are there and what ones do I need to clean?

ALSO: I noticed on the aircleaner there is a crack around that rubber seal thing might that cause it not to run? like it sucks in air???

storm_impulse

10-06-2007, 10:00 PM

the crack is not something that will make a huge diffrence. the carb itself sucks air, just as long as there isnt a crack on the intake. the motor would still run even if the whole aircleaner is off, might run alike junk but it would still run.

james9r9r

10-06-2007, 10:02 PM

Yes there is a crack/rip all around the rubber seal on the air cleaner rubber that connects to the carb.choke area?

storm_impulse

10-06-2007, 10:05 PM

still with that crack that motor should still start and run. i ran my 200x without the aircleaner/ air box *Edited**Edited* and it didnt do anything besides try to die out when it recoiled. have u tried to prime the motor then start it? take the plug out and clean it and make sure its dry. poor alil tini bit of gas through the spark plug hole. just enough to make the motor start and run for a sec. doing this u may be able to study the way the motor is acting and also try to hit the gas if it starts. see if it just bogs out and dies. if so im going to have to say one of the jets are dirty also. as much stuff as u have went through u should of hit the nail on the head by now. its prolly something simple and it has u mind boggled. thats happened to me before

RedRider_AK

10-06-2007, 10:24 PM

That crack will eventually make a difference but for all intents and purposes it shouldn't make any difference in starting the beast. You say when you pull the plug it is clean and dry. Does it want to start when you put it on full choke? Have you tried to use a different carb on it yet?

I second the idea that it's the jets. If you've got gas in the carb, and there's nothing going on, either you've got a hell of a lot of water in the carb, or your jets are so clogged that it doesn't flow ANY gas at all.

blue27

10-06-2007, 10:34 PM

# 30, 13, and 31 need to be clean . there will be a hole all the way through the center from top to bottom and some crossholes in 13 and 31 also that need to be clean. If I had to guess the #30 and 13 are clogged

james9r9r

10-06-2007, 10:44 PM

Well am I done I poured gas into the cylinder and It came out of the bottom of the head? well I see a big chunk of the head tooken out???

stoney420

10-06-2007, 10:49 PM

uh oh man that dont sound good, any way you can get a pic of it?

james9r9r

10-06-2007, 11:06 PM

Here are the pics of the chuck out of the head.

But it's been there since I got it 2-3 yrs ago and it used to run then it sat for about a year.

Does it look like we might of found a big problem?

Sqirtster

10-06-2007, 11:34 PM

From the picture, in my honest professional opinion, from many years experience, I think I can see your problem. The fuel lever is off. Try it in the "ON" position and see if your situation improves......:wondering

james9r9r

10-06-2007, 11:36 PM

No man i just turn it off in the pics they seem to think since I am getting gas to the carb it is clogged jets, or the on button on the gas cap is plugged.

@ Red Rider AK: When I choke it I can't get it to even fire.

rally4x4racer

10-06-2007, 11:40 PM

I always ride mine with the lever off - that can't be it!

check jets - you said it sat. also - choke has nothing to do with fire

storm_impulse

10-06-2007, 11:45 PM

if its not getting gas to the combustion chamber then it should have started off the gas u dumped into the cyclinder. no?

Sqirtster

10-06-2007, 11:51 PM

OK, not that. Well the head is made like that for cooling if what you're looking at is that "hole" on the bottom left side of the head. Have you checked the fuel shut-off valve, as in take it apart? Also, there is a micro screen filter attached to it inside the tank. One more thing, just a thought. Are your valves adjusted right? If they were too tight, when you pour gas down the intake, it would come right out the exhaust if the valves are too tight or bent.

james9r9r

10-07-2007, 12:11 AM

Ok so that hole is suppossed to be there?

Micro screen filter attached to it inside the tank do you mean in the petcock or in the gas tank???

james9r9r

10-07-2007, 12:13 AM

The only time I can get it to fire is when I spray engine starter into the carb or pour alittle gas into the head. It fires for a few secs then if I try to give it gas it bogs and dies I also think it sounds like it backfires at the end maybe???

storm_impulse

10-07-2007, 12:29 AM

get a shop manual and go through the motor from top to bottom. im all outta ideas. im going to have to say timing or something to do with in that area. valves possibly?

james9r9r

10-07-2007, 12:31 AM

Ok 1 last thing do you think it could be like points???

storm_impulse

10-07-2007, 12:32 AM

no cause if your getting blueish purple spark then there is nothing wrong with the points. i think it has to do with ignition firing. sounds to me like its firing right before TDC or after. are u totally sure your timing is correct?

james9r9r

10-07-2007, 12:45 AM

What do you mean by (TDC)? and I have no idea about the timing?

Could it have to do with my ground wire and my headlight hookup magneto???

storm_impulse

10-07-2007, 12:48 AM

TDC means Top Dead Center. im not really sure im just basing my knowledge on the xr70 motor cause the setup is pretty close to the same. the piston must be TDC and the cam's timing mark must be pointing to the top also. align the cam's timing mark with the timing mark on the head. if they both line up then *Edited**Edited* motor is in time. remember the piston must be TDC, this is when the piston reaches the end of the compression stroke. make sure your plug is pulled so your not fighting against the compresion, also if your not sure when it's TDC just watch the piston come up through the spark plug hole. if it starts to go back down then u missed your TDC position. there should be a timing mark on the surface of the head somewhere. can anyone else chime in on this cause i dont want to mislead him.

james9r9r

10-07-2007, 01:02 AM

anyone??? lol

RedRider_AK

10-07-2007, 01:13 AM

I would take your carb apart and clean the jets thoroughly.

james9r9r

10-07-2007, 01:20 AM

Then go on with the timing?

storm_impulse

10-07-2007, 01:21 AM

go with the carb first. clean the livin shiot outa it. if that dont work then it has to be the timing.

dizasterzrfun69

10-07-2007, 01:40 AM

i must add that i would SOAK the jets in carb cleaner for at least a couple hours if not over night. I had 3 atc70 carbs and ALL of them had the main jet gummed up solid inside. Also like 2 of them the bottom "tube" part of the pet cock was so clogged i couldnt even get a TINY piece of wire through there.

RedRider_AK

10-07-2007, 02:11 AM

Yeah, I would blast the crap out of the whole carb, soak the jets, clean them out with super-fine wire, do anything you need to get it working. I think it's something simple like your carb being all gummed up.

james9r9r

10-07-2007, 02:15 PM

james9r9r

10-07-2007, 03:04 PM

Once I clean the carb should I go with timing it????

james9r9r

10-07-2007, 03:18 PM

Ok well I unscrewed the pet cock from the carb and turned it on and nothing then I switched it to off and nothing then to reserve and gas shoots out does it sound like one of the holes inside the gas tank is clogged from when I sealed it ???

DIGGER DOG

10-07-2007, 03:27 PM

take your gas cap off and try the petcock in the on position

james9r9r

10-07-2007, 03:28 PM

I did just barley a drop comes out??? then no more come out???

Once I figure out this I am cleaning the carb and jets then it it doesnt start I am going to check the timing

storm_impulse

10-07-2007, 03:36 PM

that sounds kinda like my 200x. the only way to get a good gas flow to the carb is to run it on reserve. my on dont work only reserve

james9r9r

10-07-2007, 03:41 PM

Hmmm well then I think ill just leave it as that and clean the carb really good then put it on reserve then try to start her up if not then I will have to go with the timing like alot of you suggested???

james9r9r

10-07-2007, 03:53 PM

Is that what you'd do is clean the carb really good then try it on reserve.

If all else fails check the timing and try to start it???

DIGGER DOG

10-07-2007, 03:56 PM

It sounds like either the petcock is clogged ,and or the gas cap isint working and or one of the outlets from tank to carb is clogged try to run it on reserve.

stoney420

10-08-2007, 12:13 AM

james, make sure you can see light when u look through the tiny holes in the jets, you should be able to see light when u look through it if they are clean..if not keep cleanin em till u can, use a paperclip or some other skinny wire and run it through the jets, and yea if gas isnt coming out of the petcock when its in the "ON" position then that was your problem, did u try it on reserve at all? put the carb back together and put it on reserve and it should fire up, im not sure about the "hole" in the head that u took pics of kinda looks like it should be there but didnt u say gas was coming out of it? are u sure gas was coming out of it? i think it was probably gas from when u took the hose off and spilled a little?;
im going to say it will most likely run when u put it on reserve, you probably plugged the hole with sealent when u sealed the tank..
also i know i posted this earlier in the thread, but since u were messin with the screws on the carb and arent sure what you have them set at or what they should be set at read this link and put the screws back at the these setting for now, if you have the idle screw in too much and your push starting it then it might idle high and take off on ya you dont want that, and if you have the pilot screw to far out you'll be running lean and that can cause major engine damage, you dont want that either!
heres that link http://www.3wheelerworldforums.com/showthread.php?t=62580&highlight=atc+70+pic
turn the idle screw all the way in then back it out 2 turns, and turn the pilot screw all the way in and back it out 1 and a half turns out, if your not sure which screw is which then the one in the middle of the carb is the idle and the one a little lower and at the left of the carb is the pilot screw
hope this helped, im sure you found your problem but be sure to let us know how it goes!!
~Stoney~

james9r9r

10-08-2007, 12:42 AM

Yes we have got the problem it was mainly the jets I cleaned the big one but the one that makes it idle I can't see through. Wire wont go through but hey I got it running thanks to alot of you and thats all that matters but I still want to know why when it's on the on position gas will not flow out I think it has to be the metal pipe coming from the tank got sealed over when I put in the sealent?

Thanks to you all who helped

RedRider_AK

10-08-2007, 12:50 AM

I knew it was the jets. Had to be. Try to get the finest gauge wire that you can and clean the pilot (idle) jet out. It won't idle well or at all with that one dirty. As for your sealed pipe, get a coathanger like someone else said and sharpen the tip, bend it into a hook and jam it up through the tube that you put the fuel line on. Try to work it out. Or just run it on reserve all the time, it won't hurt anything, you'll just have no warning when your machine runs out of gas. Keep checking your fuel levels and you'll be fine.

stoney420

10-08-2007, 12:53 AM

nice man i knew we could get er goin!
good job!
take that idle jet back out and soak it over night in carb and choke cleaner or something similar, if you have a air compressor or know someone that has one take it and blow air through it too that works most the time but im not sure if it will work if the wire wouldnt even push through it, or was the wire just too big to fit through the hole? anyway, if you cant get it cleaned then just buy a new one there only a couple bucks, im not sure what places you have around your house but try calling some local small engine shops and etc..theres a number on the jet to tell you what size it is..
also did u see this post i posted yesterday? if so then did you switch them?..
heres the post, reply back asap

hey man i was just comparing your pictures to the ones that brockey posted and u have your hoses on wrong it seems..switch them at the carb, the one thats on top switch to the bottom and the one on bottom switch to the top
im assuming one is for reserve so i think it should still be running the way u have it tho unless u dont have much gas in it?
...

did you already switch them?

james9r9r

10-08-2007, 01:01 AM

Yes I switched them I asked that Brockey guy to take pics and I looked at others and I had them on backwards so I switched them the way they go. but my other problem is I want to get gas flowing when in the on position???

NOTE: I soaked the idle jet again and blew air through it and nothing so I'll soak it overnight and see what happens...

It's running now on reserve but it doesn't have much power because of the fact the idle jet is clogged and its not getting enough gas to the engine to function properly.

Thank you for your help also.

stoney420

10-08-2007, 01:14 AM

ok cool, yea soak that jet over night and then run a skinny wire through it and try blowin it out with air till u can see through it and you should be good to go, also make sure you have that pilot screw (the lower left screw) at about 1 and a half turns out if you have it out too much farther then you will be runnin it lean and can cause engine damage, just screw it in all the way then back it out 1 and a half turns, no point in messing with the idle screw tho until you get that jet cleaned out, after you get the jet clean then just warm up the engine for a couple minutes and adjust the idle so its idleing at a good rpm, you dont want it do idle real low but not so high that it takes off without givin it gas, im sure you know what i mean, its easy stuff, and as for that plugged fuel tube use a coat hanger or somethin like red rider said and work it out, or just run it on reserve, it dont hurt nothin obviously, just if you do keep it on reserve make sure you dont run out of gas cause u have no backup gas, once it runs outta gas on reserve its out! keep us posted man,
glad we could help,

Well I rebuilt my whole carb on my 1983 atc 70 and the damm thing takes forever to start. I have to push it in gear to start and when it does run it still has no power and boggs, almost dies when I put it in 1st gear and fouls plugs if I can get it started?

NOTE:I am missing the little cap that goes on the choke lever I am thinking I am sucking air threw it. Also it won't idle at all unless I push in where the cap used to be with my thumb???

Did you ever change the rubber boot that goes between the carb and air cleaner? Did you ever get the pilot jet cleaned out? Does it idle? Does it die if left idling for a few minutes?
Also, try switching your gas lines back the way you had them, then see if gas flows in the ON position. If not then clean your petcock.
Buy some inline clear plastic fuel filters. $2 at any hardware store. When you take your lines off the carb and turn the gas on/reserve does the gas flow fast and steady?

Yes the rubber boot from the air cleaner is damaged but I repaired it.
pilot jet is cleaned out all new jets.
It wont idle at all.
if I can get it started it will not have any power and will be bogging bad/cutting out

Yes the gas flows out steady but doesnt shoot out but it does shoot out a little

I doubt it needs a new carb, carbs don't really wear out...

But, since your having so much trouble and don't seem to know how to fix it, I guess you ought to buy a new carb and then you can rule that out. Then buy a set of points, coil, new plug, on/off switch..... OK, I'm just being sarcastic, but there is obviously something stupid going on here and you may as well grab a new carb and hopefully that will fix it.

Try to stick with one post bud, with everyone here, it will have to run sooner or later....

Did you clean the petcock? Those suckers can clog up real bad if left sitting for a while. There is also a thin screen filter in there. It only takes a few minutes to do. Do that and post back. We'll get this little trike running.

OK do what?

The lever that you turn to RUN/RESERVE/OFF probably needs to be taken apart and be cleaned. There should be a thin filter in there that needs to be cleaned also. Spray some carb cleaner through both outlets. If they are clogged run a piece of wire through them. Guitar string works great.

Its where the fuel shut off valve is. unbolt that *tip the tank so none comes out* and clean it.

I think the petcock on the atc70 is on the carb like the atc110. you can plug the fuel lines with bolts to keep gas from leaking everywhere.

Yes I know where it is, but could it really be the petcock is plugged up and its making it not get enough gas through there into the carb and bogging ?

Yes. It can definitely restrict the gas flow if it has trash in it. It will only take you a few minutes to do.

Yeah it just takes a small screwdriver to take off the petcock cover and clean the screen out. Every time I check an old Honda carb, it's always got rust/crap in the screen. Make sure the o-ring is good and doesn't leak, if it does, seal it up with Motoseal gasket maker.

The O-Ring is brand new from the carb kit and the screen has been throughly cleaned?

Well this was blocked on mine. I took it apart and sprayed it out with parts cleaner. Switch it thru the postions as you spray the different holes. Also on them little lines one is marked r for reserve and o for on. With your tank off, turn the vent off and turn the tank upside down and blow air in the lines. I used my mouth and blew in one line and gas sprayed me in the face from the other, there that will determine if those lines are plugged. On the pics I posted for you between the carb and intake I have a piece of red plastic. This gasket was plastic and gave out and my bike wouldnt idle and was a devil to start.

Are you saying to take the gas tank off and turn it upsidedown with the gas cap on
off position then blow air threw the metal pipes coming from the gas tank???

Brockey

10-21-2007, 10:28 PM

This was a crude way of finding out if the lines were blocked in the tank. It might of been easier if the tank was empty, but it was full. Yes turn gas cap to off and blow air thru the lines with the tank upside down. Check that gasket aswell.

james9r9r

10-21-2007, 10:32 PM

Yes when I sealed it one was blocked but I unclogged it and now I have gas in both lines and I have already blew air through there ?

Brockey

10-21-2007, 10:34 PM

Well check the plastic gasket between the carb and intake. Mine wouldnt idle, and I use to have to push my 70 and jump start it.

james9r9r

10-21-2007, 11:55 PM

Well the rubber gasket between the carb and the intake looks fine ?

Not the air filer side. The engine side.

Well today I made a decision and tryed gapping my points well I didn't use a feeler gauge but When I turned the rotor counterclockwise I lined up F mark on the rotor with the index mark and then loosend the point screw and pryed with a screwdriver and opened up the point just a tiny bit then tightend the points screw and pushed the 3 wheeler and it started and purred!!! like a kitten and ran for awhile but now the plug is really bad carbon fouled. what is causing it to carbon foul plugs ?
