OK, I have a decently running 85 ATC110 - and I tipped it on it's rear to change a front tire I was having difficulty getting off.
It was upside down for about 3 minutes, once to get the tire off, and once to get it on. When it up tipped up, fuel was running out of some long black plastic lines. Not sure exactly why!

Anyways, now it won't start! Pull and Pull and Pull...nothing.
Checked the spart plug, not wet...can smell fuel, but it may just be the fuel on the floor...kill switch is on....tried with/without choke...nothing.

Any hints? Used to start on 1st or 2nd pull. Must be something to do with leaking fuel?

Thanks!!!

 

the ball float in your carb is cutting off the fuel some times boucing the bike a round a bit works or you might have to drain all the gas to get the ball to come down.
