George, I sent you a PM….. Thanks!
Mumbles, thanks for the great photo work!
I was always leery about removing the flywheel
by backing off the nut against the rope sheave
on that style set-up…. I could see the sheave
breaking easily!
I only check my messages about 1 time per day and I did get yours and I responded. I read some of the thread on the spark plugs. I quit using Champions…I had issues with them in other motors. I now use the NGK AB-7 with great success. The Champion D-9 and the 509 are the same and work great in PO’s. It is suggested to close the gap on Evinrudes of that era, so I run the Evinrudes at .020 and the PO at .025.
