Thanks guys,

I l see where I was missing anything. That confirms my thought that the bronze lower crank bushing was all the seal there is for the lower end of the crankshaft. I put it back together and tank tested it and I was able to get it close. When I took it to the lake for a run it overheated 😡 even though it was pumping water like crazy. The upper carbon seal doesn’t appear to be leaking. No oil on the mag plate and no apparent sound of a leak. Something is certainly amiss though. I need to figure out what my next move is now.

I was running it on 16:1 mix, freshly rebuilt pressure tank and new o rings in the fitting. It holds pressure for days and doesn’t leak. New fuel lines, carb cleaning and new carb gaskets, spark plugs, plug wires, points, condensers, water pump impeller, and fresh oil in the gearcase. Not sure yet if it hurt anything, but I’m at least going to pull the head and have a look at the bores, cooling passages, etc. I need to get a new head gasket on the way.
