I just got done cleaning the carb on my yfm80. I put it back together and can't get it to fire. Its getting spark and its getting fuel to the float bowl but i'm not getting fuel to the head. It seems like instead of sucking the fuel in its blowing air out towards the air filter. any help will appreciated. steve

 

How about some more info? Was it running before you took the carb off, what else did you take apart or change, etc.

 

I think i figured out the problem today. stupidity on my part. I had replaced the head gasket and i think it got out of time. I had put a zip tie around the sprocket and the cam chain but evedently when i was taking it off, it must have jumped a tooth. But thanks anyways. steve
