  • 1990 sp problems

    alright, Originally i had a hose on the bottom of the engine come loose and my sp flooded up to the fuse box, i pulled the plugs checked for water in cylinders seemed okay, removed exhaust header and reinstalled hose, ski started up fine but either right away or a short time later it began back fireing through the carb at WOT, so i went ahead and changed the rotary valve case seal, oil pump seal and carb to case seal per the suggestion of my dealer, no fix, i then checked the fly wheel case for water or bad wiring (also per suggestions form dealer) still no fix. i have also changed a clogged oil filter and readjusted the carb and checked all grounds around battery.........so now ive been told it must be the seal that sections my engine in half horizantaly......any suggestions before i tear this motor apart?
