I did use a timing light after setting the points with Franks’s tool and an analog multimeter. As i recall, i thought i nailed it perfectly setting the points with the meter ,then when i put the flywheel on and hit it with the timing light, it would be off. Start Over. I did this a bunch of times, and may have meant to get the one set of points even closer but never got back to it. It is JUST outside the right mark and runs pretty good for 90/92 psi on both cylinders. I will do a decarb on it when i have some time and we can get the motor to a lake. That will most likely help a bunch.
I would think that if the mag plate had a bit of play/wobble in the bushing, the timing would move around a bit when the timing light was being used . I recall not feeling any play in the mag plate or upper crank bearing.
I had written detailed notes on all i did and gave to the owner, he gave me a funny look when i asked for them, like he doesn’t keep things like that.
I added 1.5 oz of Seafoam to the fuel and will hear back Tues pm how his shrimping trip in the sound went.
Thanks, Jim PSB
