So again with this plug.. I definitely intend to move my timing from 35 back down to 33.. but again this white strap and relatively white clean insulator (lean) and the dark base circle (rich).. :BangHead:.. View attachment 1715480775
That strap says you have a little too much initial. But, I read where you pulled couple degrees out. It is very possible to be lean or rich at idle and be opposite at WOT with those style of carbs.
