Re: Motor running faithfully now, but.......
I use a Diamondfire E3 or was it E3.12 plug. It's shorter by design but when my older plug pulled out black this E3 pulled out brown.
I also use a solid wire spark plug wire. I believe Norman may still have come copper core wire available but that was a few months ago.
I got my wire at NAPA but it seems not all NAPA's carry solid metal wire.
You have found the fountain of youth. Ride and forever stay young.
