    Rev tech 100" foiling front plug.

     I purchased my crate motor and had problems with foiing  front plug since installed, I had it looked at and it ran ok for around 20 min.

    then it started foiling the plug again.  Any suggestions would be appreciated.

    Thanks Don

    Re: Rev tech 100" foiling front plug.

    dk, you have to determine what's making it foul. Powder black: too much gas. Glossy black: oil fouling.

    It's not likely oil, with a new engine, so look into fuel delivery. Also make sure the heat range of the plugs is correct. You might want to run a hotter plug for break-in...


    Don't force it, get a bigger hammer.
