    I have searched and at no avail I couldn't find my answer. I have the Grubee Skyhawk 66cc angle fire. The manual says to run 3 prong spark plugs for complete combustion. I find many of you are running single prong plugs. Are any of you running single prong on a angle fire/slant head?

    The 3 prong plug offers better exposure of the spark to the air/fuel mixture but is not essential for "complete" combustion. With a single prong plug you can file the ground electrode on both sides of its end for a pointy tip that will do the same. I haven't done that yet on mine as it runs very good. I may though.

    Regardless of the plug, you'll never get complete combusion of the mixture due to the nature of the 2 stroke engine. I've never used a 3 prong and don't intend to do so anytime soon.
