I have a 96 Bayou 300 KLF and it has sat for several years without running because we got some new polaris quads. Well when i put gas in it it leaks eventually out of the airbox for some reason! Took the seat off and turns out gas is running down from the carb into the airfilter then into the box and onto the ground. Any suggestions on what exactly could be the cause of the problem and how to fix it. Kinda trying to restore the thing. PS: It dosent start.
