the carb is leaking gas out of the vent line right under the fuel line it only happens when the quad is running so what in the heck could be causing this??
Btw i did just get done messing with the jetting so could that have something to do with it???

 

Sounds to me like your floats are out of adjustment you could have bent the float tab that goes to your needle valve and seat on your fuel inlet or your needle and seat are worn out I would try adjusting your floats first if that does not do the trick replace the needle and seat.

 

what do you mean adjust your floats??? Also i never opened the carb i just opened the small bowl on the bottom to get at the main jet.. also if it was a stuck float wouldent it leak all the time??

 

I do not think the float is stuck or it would leak all of the time. I think your floats are out of adjustment . When gas enters your float bowl the floats float on top of the fuel and the tab located at the base of the floats rises up and closes off the fuel inlet needle and seat. If the tab is bent down to close to the float the fuel will leave the bowl thrue your overflow tube before the floats can turn it off. I think a simple float adjustment would fix your problem.
