So, my sons LT80 stops running, I spend over 3 hours cleaning the carb. It will run with the choke on, but only at idle. I am convinced it is the carb. I finally think there might be something wrong with the Vacuum line to petcock, but that seems to be working also. So I take the other rubber hose off of the carb, and whammo it runs. This hose just seems to go to the bottom of the frame and is zip tied to it. It seems to be clogged? Now my question for anyone, why would a carb need a breather line, at least that is what is seems to be?? Or is this hose supposed to go somewhere else??

 

The vent line needs to breathe. That's just the way it is. [img]i/expressions/face-icon-small-smile.gif[/img]
