Hello all.
I have read a few posts about the concerns of the C7E plug being too long and extending into the combustion chamber by a couple threads. I have a simple solution that only cost me 80 cents. I have read that a few people have removed some of the head to allow use of a shorter plug but I took a different approach. I bought a copper gasket that is the correct thickness to make the plug fit perfectly in the head. The two threads that were visible are now in the head where they should be. Heat transfer should not be a problem because the gasket is copper. The copper gasket is for a high pressure banjo fitting. Napa part #26982 $0.80 each. This may be a coincidence but my Whizzer even started a little easier even though the temperature was only 33 degrees F. Still too cold for me to ride.
I have enclosed a picture. Hope this helps.
