Ok i got a 90cc yerfdog atv, it starts up fine and will run great for a few minutes, then once its warm it will bog down when i give it gas. I took the air filter off so i could choke it with my hand it, then it will run fine as long as i keep it choked, any help would be greatly appreciated, i have cleaned the carb numerous times and the fuel flow is fine, i also bought another carb and that did not work.

 

Could you see light thru the pilot jet and the holes in the side of the main jet holder when you cleaned the carb?

 

yes i thoroughly cleaned the carb

 

Plugged pipe?

"fuel flow is fine"
Yes but for a long enough time? Plugged fuel cap vent?

 

so fuel flow is fine pipes not plugged, recleaned carb again runs about 5 minutes, then starts to bog so i choke it with my hand then it runs like a champ for a few, also if i let it cool down it will run great, it has and auto choke on it, suspecting that is bad any way to test it or how it works???
