Hi, I don't think there is much to be gained by indexing on our motors, however
I have always felt it important to use copper washers to regulate the thread
ingagement in the head. I think its important not to have any of the bottom
threads of the plug appearing in the combustion chambers, those sharp edges can
act like a glow plug, a good cause of pre ignition.thx

best.

Mostly a carryover from high perfornace two stroke motors where transfer
port swirl could play havoc with a spark. Or at least people thought it did.
One more thing to fiddle with.
