Thanks for your lead on a motor repair. I worked with the engine again yesterday, and again the eccentrics. I did note a problem with one side that the crank was coming down way low to the point it was hitting the deck on my bridge, and I think elsewhere. I re-adjusted it and it appears this time it ran smoothly in both directions. I will be running it again today to make sure it is running like it should.
I'll comment later.
Thanks to all.
