'85 200X rebuild won't run w/out choke on

[dougspcs]

Man these guys have you hoping with ideas..

Don't get your head in a knot over this jet VS that jet...stock jets and settings will make it run. The rest you can dial in later!!

KISS (keep is simple stupid)..

If it isn't running, there is something basic wrong..stay on that course and don't get overwhelmed from all the input..

You know your close..just slow down and you'll figure it out.

How about that timing??

Gonna check timing and intake when I get home. I see your point, Doug, but I'm willing to take advice of guys that know a lot more than I do about this things.

I just fixed a 250 suzuki quad tonite, the lad said it only runs with choke on and dies when you give it throttle... i rolled my eyes and said ok. BEEN THERE
Its running lean, the choke richenes it up restricting air flow,,, drop your throttle plunger needle down 2 slots or one at a time and you will notice a BIG difference, dropping the needle clip richens it up !
I droped his from 2nd notch to 4th notch and ran like a champ, took it up and down the street with a big smile on.

any word on this?

[Qdude79]

Not yet. I'm hoping the new jetting will come in soon. Need to check for air leaks and the CDI while I wait.

Sidenote: I wrapped the header last night and fired it for a few minutes to burn the water off. Being dark, I rolled it outside the garage for fresh air while running and noticed a glow from where the header meets the head, almost to the first bend. To me, this indicates a lean condition. We'll see...

Alot of the time a glowing red header is because of improper spark timing or rich running condition..one or the other will cause combustion to take place in the pipe instead of in the cylinder.

Also your replaceable jets are not for idle mixture control..

Again..back to the timing check friend!!

[Qdude79]

Agreed. Timing, along with air leaks is still very much on my to-do list.

did you notice it smoking or smelling very rich? pull the plug out and post a photo. i want to see if your lean or rich. i have seen this caused by both lean and rich conditions depending on what is happening. do NOT run the bike again till we figure this out. it could melt pistons and such...

[Qdude79]

Will do, when I get home in another three/four hours.

I am having a very simular problem with my 200x running a supertrapp so I am following this closely hope he and me have good luck and solve our problems soon, mine is a little worse though because I am also sure I am burning oil and either need to do valves or piston rings I think at first I thought it was just oil burning off from when I layed it down for a cpl seconds to paint the bottom of the engine but it hasn't stoped and the oil dropped in it

Snuck home quick. Here ya go:

your running lean

check your float adjustment in the carb. also is the filter on the petcock cleaned up? it looks like your not getting enough fuel and i am thinking something is restricting flow. so check the petcock (take it out of the tank and clean it and confirm no clogs and screen is clean) then take carb off and check float. the easisest way to check is to have the carb upside down and the floa sectin that is sticking up should look to be perpendicular (sp?) to the case of the carb where the bowl bolts to. if it's level to that, you should be "ok" of not adjust the tab till it's level.

i thought it wwas lean, but wanted to view the plug to be certain and that is definatly signs of lean conditions.

[oscarmayer]

one more thing you can do is put the clip 1 up form the bottom of the needle. that will richen it up some.

the mixture screw, turn it in till it stops and then turn it out 2 turns. see what that does.

[Qdude79]

Thanks Oscar. The fuel petcock is clean, as it was just installed.

I'm thinking that the float level is a likely culprit. I don't recall doing ANY adjusting or checking of the float level. I'll try the needle change, too. Would you still suggest going with the 42 pilot and the 115 primary?

I'll work on it this weekend, and yes, I WILL be checking timing and air leaks for certain.

[oscarmayer]

try the float and needle first and go form there. I still think you'll need at least a larger main, in the end, but that may be it.
