Stupid question but what is spark plug indexing?
Not a stupid question at all. It positions the plug when it's tightened so the ground strap is not in the way of the flame front spreading out into the chamber which makes a faster burn which needs less timing for the mixture to be spent at the perfect crank position for max power(less power wasted pushing the piston over the nose against the compression). You make a magic marker mark on the outside porcelean shell & use the right thickness washer so that when it's tightened that mark tells you that the ground strap that you now cannot see is not blocking the open part of the chamber
