    Oil on plugs?

    What would cause a GPR to have a good amount of oil on the spark plugs and on the FA's?? Does this mean I am running too much premix?? The plugs are wet with oil... I am running Amsoil Interceptor @ 40/1. Any ideas??

    Clint, are you looking at the plugs after a plug chop or after idleing? If you are looking at them after idleing they may have oil on them.

    The factory oil pumps are variable style pumps that deliver different amounts of oil at different throttle positions. When you pre mix you are delivering the same amount of oil at all times.

    Has the ski back fired lately that may have caused a reed to break?

    Actually yes the ski had a small backfire last week... I am changing out the reeds today and will see what they look like.
