Oak...thanks. I really appreciate that but I don't think I'm quite up to it. For one thing, the next 2 months are extremely busy for me so I don't really have the time to devote to it, which would undoubtedly take me 10-20 times longer than someone who has the experience working on these. Believe me, I do take lots of pics and notes when I do virtually anything on the Cub, but I think I'll get a rebuilt short block and leave the work to my brother's service station. IF it was in the middle of winter and I had hardly anything else to do, I'd perhaps be more willing to pursue what you suggested. I've already spent several nearly full days over the past week or so and am right where I started, and yet have spent the money for a new plug, points, condenser, and coil. None of those are at the heart of the problem. I've always taken great satisfaction out of being able to successfully complete jobs on the Cub over the years, but this one is just a bit too much I'm afraid. Still..you have tempted me
