Just curious about this.
What should I expect to see when checking the timing on this motor @ 1000 RPM in forward gear and underway om the lake?
I have done a lync and sync per the "Clams Canino" routine as suggested on this forum and feel confident that I am "right on" with the initial settings.
What I am seeing is approx 3 degrees BTDC.
