Got a big problem. Started my sled and ran it for about 3 min, loaded onto trailer then headed for the lake. Went to start it without priming and didnt fire up. primed it 3 times and it didnt fire. Open up the hoodand all hell broke loose! i had gas spitting out of fuel pump and running out of exhaust. Let it set for awhile went back out took out spark plugs and pulled and ALOT of gas came shooting up out of cylinders. Why would i have so much gas flowing when there shouldnt be?
