    black particles on spark plugs??/

    changed plugs on my 98 faststrike 115. i noticed that there was a fair amount of black particles on the plugs, i hope this is just carbon particles and not part of the internal engine. i dont believe the engine has ever been decarbed.

    i know its not normal but has anybody seen this? guess it might be time for a decarb job

    Have you been adding seafoam to the fuel?
