So my 2002 yz426f was having problems starting recently. Before this I have always gotten it started in 2-3 kicks. it was hard starting for a couple weeks then (at the track) just quit and will not start. Things ive checked: carb is getting fuel, New spark plug. When I took of the inspection covers to check for valve clearance (which were good) I got about a gallon of gas out of the engine case. Ive got the carbs out to clean them now. any other ideas on what could be happening? I'm at a loss!
