It's another ride? 
Anyhoo. Bought a quad almost a month ago. Ran like crap, cleaned it, adjusted. Runs just about great. Got my carb rebuild kit in a week ago, and few more misc parts that were missing today and rebuilt it. 99.9% is runs great.
Except it will die as soon as you open the choke. It's been in the part choke position since I bought it, riding that way, and it idles great, off-idle is great, part throttle is great, WOT is great. Before I bought the kit I had slight vacuum issues, so I had the pilot jet turned out further than it should have been (4.5 instead of 2.5 that it should be) just to get rid of the off idle stumble issues due to the vacuum leaks. Ran great like that. So rebuilt it, everything is adjusted fine, no leaks, runs great.
But won't run w/o the choke pulled part out. It's clean, no blockage, adjusted right. Now it came with a new needle. So I checked the old one, it's adjustable, the top of the needle has 5 grooves to adjust lean/rich. It was at the very top groove, which is most lean setting. Book says stock is in the middle (3rd grove), I put the new one there, and ran super rich. So put it where it was (top groove), and all is well again. Spark plug looks fine, exhaust is clear.
No friggin idea, EXCEPT MAYBE, there's o-rings, a spring and the choke pull screws into the body of the carb, and there's a plastic boot thing isn't nice and snug around the shaft the knob is connected. But even so that part shouldn't have air or fuel passing by it, as the base of this knob is what goes into the carb body where all the orings and things are.
I mean, really, leave well enough alone, it rides great. Just erks me.
Oh, it's an 89 Yamaha Big Bear 350 4x4 with auto clutch. Signed up at one atv forum, it's dead there, signed up at another, seemed better, but it's dead there too. And they mostly have newer stuff, and aren't very 'techy'.
