110 problems....STILL....

[250RWANTER]

okay, been busy so havent had time to mess with it lately (1980 honda 110).
Finally got the carb kit and put it all back together....still does the SAME THING!!!

fires up and idles at HIGH rpm's and poors blue smoke! and back fires here and there. I have the idle screw at about 1 3/8's out and the air mixture screw at 1 1/8 out from all the way in.

Jets, gaskets, etc are all new and the clip is on the middle/third notch on the top.

When its does start up...it'll idle high...then come down a little then up and stay there....


Everything seems to be fine otherwise...
Any ideas? Really getting frustrated.
also when I turn the bars sometiimes (while its sitting there) it idles a little higher.

well i know you said you had new gaskets and all that, but it sounds like it has an airleak in the intake someplace, or maybe something is cutting off the gas flow so its not getting all the gas it should be, check your fuel lines, and all that good stuff, and make sure gas is flowing at a good constant even flow.

[hondatrikesrule22]

The same thing happened to me, it would rev really high when I would start it. Try this,(it worked for me)make sure the slide, and needle are properly set in the hole. Because I yanked my carb. and didn't check the slide causing the motor to race. Just an idea....

[250RWANTER]

Feul lines are clear, tank is clean...I've cleaned everything real good. Taken the carb apart a million times, just to double and triple check it

How do I check for an air leak?

I'll try anything...sooner or later its gotta run right!

[250RWANTER]

as far as the slide and needle...i checked that too, but they seem to be seated properly and in the right notches on the carb neck.

Im pretty sure that if the idle goes up when you turn the handle bars back and forth that the throttle cable is not adjusted right or is shot. My 80 110 I had when I was a kid did that after I got it back from a shop that adjusted the valves and cleaned the carb. They didnt know what the hell they were doing and dad ended up readjusting the valves and the throttle cable. I have a neighbor that has a Yamaha dirtbike that did the same thing and his cable was shot. He put a knew one on and it was fine. Just a thought. I know im not the only one that has herd of this symptom. The hadlebar thing is a dead give away on the reving. Blue smoke I dont know. Air and fuel isnt right. I think new carbs for that thing are only $100-$138. Just a thought.

[250RWANTER]

maybe I'll check the cable...but how do they go bad? I mean it still moves freely inside the tube and all.
Any othe ideas?
I really want to get this thing right. :confused:

[smokinp]

the exact same thing happenned to me with my atc200,check your cable and spring and make sure that it is not bent or the tank is not resting on it causing it to bend.

[plkmonster2]

Make sure that the cable is routed right. If it isn't, it is too short when you trun, and it pulls it from the carb. Blue smoke is definitely oil smoke. Either your rings are bad, or your valve guide is leaking.

[250RWANTER]

even with the tank hanging off and the cable hanging free it does this.

Also, i thought blue was too much gas?

[plkmonster2]

I'm positive white is too much gas..... Not 100% sure though, but my 79 110 poured blue smoke, and it was oil. You can really smell that oil smoke, its like a sweet gagging smell. So when you turn at random it revs? Make sure that the thumb throttle isn't hitting anything. When you turn, does the cable start to tighten up?

[250RWANTER]

It revs when I first start it...its like...*pull.....REVVVVVVVVVVVVVV*
No matter where the bars are.

[plkmonster2]

Try to lower the idle a bit. A 185 I was working on has the same problem. Also, lower the needle one notch. (Raise the clip) This will keep it from getting as much gas at first.... I still think it has an air leak though. Spray starting fluid around the carb, and intake seals. It will rev up more with the starting fluid if it is leaking. I think the extra fuel and air are making it rev high.

I had the problem on my 79 but mine didn't want to idle.
I changed the gasket between the head and the intake manifold and it runs good.

[hondatrikesrule22]

I am having some trouble too. My 110 fouls plugs alot, what do I need to adjust? Also, I can only give it 3/4 throttle, after that it bogs,why? And,bigred110, did you have any clearance problems with those 25" tires? thanx

[bigred110]

Also, I can only give it 3/4 throttle, after that it bogs,why? And,bigred110, did those 25" tires just bolt up? thanx

My 84 was having that problem and it turned out to be the float was getting stuck on the drain tub. Only 1/2 throttle then it would die out.
My 79 was having the problem to but it would lean out(plug was white) I couldn't get it running good, then I changed the gasket and it kicks ASS! now.
The problems would only occur when the engines where warmed up.

The 25" I got from a friend and he got them off a 200M I believe. Only thing that I needed was one hub, he threw the other one away :( . The tire only rubs when I lean on the fender. They're 2 ply tires and I run them about 3-5 psi and they are just bad ASS!. I just can't slide the back around as easy because it made it little tipsy.

[hondatrikesrule22]

What kind are they? And how wide are they? They wouldn't fit on the front I suppose? If thats the case I have some forks that are extended 3". thanx

[bigred110]

The tires are 25X11X9 and they're just regular nobbie type of tire.
The front is a 22X11X8 nobbie that is about the same size as 25's :cool:

[250RWANTER]

so should I try changing out the gasket between the head and the intake? What if I put some silicone on it...would that work for the time being, just to see if that IS the problem?

Lowing the idle does nothing.

you mentioned the float getting stuck...was that in reply to me or someone else?

Also....if its the cable....I should be able to disconnect the cable and if it still does it...the cable is fine...correct?
But if it starts up and runs fine with it disconnected, guess its the cable, right?

[hondaATCman]

Hey, man I don't think you're ever going to get this thing to run right :D

To see if you have an air leak, start the engine and spray some WD-40 around both ends of the intake tube (the piece of pipe that connects the carb to the engine) If you have a leak the motor will react differently and usually settle down when you spray it with WD-40. And yes you can use silicone for a temporary gasket, just don't use too much.

To check the float, turn the gas "on" or "reserve" it doesn't matter and let it set for a few minutes. While you're waiting, check and re-check yor vent hoses and make sure they're not plugged up. Ok, if the float's stuck gas will be coming out of one of those vent hoses. I was working on a Kawasaki Bayou 220 and it just would not run right. I took the carb apart and everything messing with the float and cleaning the jets (gas was running out of the intake tube, not the vents) BTW, it would not run off choke at all...just full choke with no more than 1/4 throttle. So finally I looked at the vent hoses and found one them melted shut where it had hit the exhaust. I cut it off right above the burn and the machine ran like new. Oh, BTW, the vent lines on a carb not only get rid of extra gas in the bowl but also lets the carb breathe.

Last thing...before you buy a new throttle cable, soak it in a bucket of used motor oil overnight. Make sure the cable is completely submerged when you put it in and when you take it out hang it up so all of the excess will drain out. When you put it back on it will work better than when it was new.

[bigred110]

If you lower the idle does the engine die?

Go press the throttle and try hear the throttle opening and closing. If you don't hear the throttle close you might have a bad cable or the plunger(sp?) is not seating correctly.

Soapy water will help to find air leaks.

You can use silicone just don't to use to much like HondaATCman said.

What part of So. Cal. are you from?

Here's my 84 110 :D

[250RWANTER]

Yeah, I can hear the throttle opening and closing. If I tweak the idle, it doesnt change it...although, I havent tried to totally kill it.

I am near Ventura, Ca. :D

your 110 looks sweet! :beer

[Vealmonkey]

250wanter, Check to see if the slide is going all the way shut. Just because the slide is operating doesn't meant that it is all the way down, ie, at idle. Put your finger and visually look into the carb intake and see where the slide is, then disconnect your throttle cable and see where your slide is. If the slide is in the same spot, that is ok, if not your cable might be short or check for something down the carb slide tube that coulc be hanging up your slide from going all the way back down. And as for the needle on the carb, raising the clip on your needle lowers the needle into its guide shutting off the flow of fuel more, not lowering the clip to raise the needle, that gives you more fuel. If you just recently just bought this atc, the carb might have been put together from several carbs and it could have a wrong slide. If you have a shop manual, it should tell you the starting points on where the fuel air screw should start at and most manuals usually say to start the needle clip in the middle notch. You could also have a different needle. Different slides and needles cause the carb to react differently. The honda shop manuals say to set the idle with a tachometer, just try to set it by ear as best you can. Keep us posted as to how it is going.

my 110 has a leak in the intake just havent gotten around to fixing it
it rev's really high by itself also i said you had a intake leak the 1st time you had problems a week ago

[JackFlack]

Blue smoke is Oil burning. You have bad rings, Valve guides or a hole in the piston.
I got a 110 along time ago that someone had used the wrong spark plug. The plug was to deep and put a hole in the piston. The thing would start up fine, rev like mad, and blow blue smoke.( Just like yours does)

You will never get it to run right untill you find out why it is letting oil by. Your best bet is to redo the top end.(New Piston rings, and have the valves done.)
