Hey, newbie here. Running a 97 formula 500, never had any problems, until now. Running slush, revs were high, then machine died. Removed clutch side plug, plug looks like it is sandblasted. It runs only when clutch plug removed, other plug looks fine. When both plugs in, and trying to start, starts for a few seconds, then back fires, then the intake foam launches into the air. Any ideas what coulda happened.:plain:

did you check the compression in the cylinder ??? i am pretty sure that you blow the piston , the piston melt down you probely have and air leak you engine run to lean

ya thats not right
