Fuel: I'm told (thanks fearlessfred) that the diaphram in the petcock can go bad/crack/pieces broke off and that allows fuel to go down the vac hose and into the motor.
I have been trying to sort out why you say a bad petcock will flood an engine when all carbs have floats that shut off the fuel supply, so a faulty float will flood an engine regardless of petcock or not. Or am I missing something else?

Carb issues
Hey i have a 95 LT80 and it sat for a while i cleaned the carb and got it to run. I had to baby the throttle. After a while it would die out. Soo as i was cleaning the carb i noticed the float had some fluid in it idk if thats supose to be there i did not buy a new spark plug yet. But i did order a whole new carb for the bike and i also noticed the fuel line on the petcock is full is that getting to much gas should the fuel line have a bubble in it

Move the needle down a notch or to and make sure the auto oil pump is working properl

LT80, well, I dont have a fiber disc that came with the rebuild kit, only 2 very small o rings and only one of them fits on the needle and it just doesnt seem like that should go on there. I've had needles that had a small aluminum washer, do you think that wuold work? Also do you think that the needle position would make the quad do what its doing. I really have to have the cable adjusted way out, basically holding the throttle open to about 1/4 throttle otherwise it doesnt run. I've read posts where people say that their bike will only idle with the choke on, mine isnt like that. If the throttle is release all the way, even with the idle adjustment all the way in, it will not idle. I will not sell the bike the way it is because its just not my style. I want it to be in a running state that I would expect one to be. I sure hope you can help because from what I've read you are the guru on the little 80's.
