So my dad gave me his 1987 550sx to tune up for him. It wouldnt start so It has been sitting since last season so I assummed it was the starter. charged the battery and still nothing. There was also still a bunch of water in the hull so i siphoned it out. On a hunch i reached under and tried to manually turn the prop. Notta the thing was siezed up. Since it ran last time anyone touched it I figured the water had rusted into place. after some banging and pulling I got the motor to spin free and the starter cranked it over just fine. but it still wouldnt start. I pulled the plugs cleaned and checked there was spark and sure enough there was. Compression checked out too. so i grabbed some starter fluid put the plugs in and it fired once or twice but not enough to start. After that no more sparking. I pulled the plugs and they were covered with this muddy looking fluid. I left the plugs out and turned the motor over and sure enough this same muddy fluid came flying out of the spark plug hole as the motor turned. Every time i cleaned the plugs i could get one or two fired then the muddy stuff would close the gap and foul out the plugs. I assume I can get the motor to clean itself out if i can get it to start up... might not run too well for a bit but it should work itself out. but i cant get the plugs to stop fouling long enough to get it to start. Are there any foul proof plugs for a jet ski of this type? I know they suck but i just need it to clean out so i can put the good plugs back in.
