Well, after a day in the barn,I think there is a reasonably happy ending! Thank you all for the suggestions. I bought the motor last fall, ran it once and realized I had some work to do. I think I was flummoxed because there were multiple issues... all the seals were original and completely shot, including the upper and dreaded lower crankshaft seals, which I knew. Lower unit leaked like a sieve and it turns out the the mixture was really rich to overcome the blown lower crank seal and the timing was way late so it was dumping lots of un-burned fuel-oil mix. Total oil slick. So you guys that mentioned that were right on. The motor had probably been running badly for a while and the carbon build up was horrendous. I set the points/timing after looking at the vid Crosbyman put up above, put the lower unit back together pressure and vac tested it, put it in the barrel and fired it up. When I gave it the sea foam treatment it was like the end of the world! thought the neighbors would call the fire department! And it made some pretty thick stew in the barrel. And, given I am in Vermont, I got to do it in a snow squall! rinsed it out and leaned up the the fuel mix a bit and its running pretty good. didn't get the boost in compression I was hoping for after the sea foam, but if it runs okay and doesn't make a mess, I'll leave it for now. Maybe next winter I'll do the rings and anything else wanting inside. Thank you all again.
