Bad gas is what eventually led to the rebuild. Somebody dumped water and debris into one of the gas tanks. And its always possible that the gas I put in afterwards has also gone bad from sitting around for a couple of months. The spark plugs I do plan to check asap. I think there is a gapping issue.

That's what I forgot! The base gasket! And yes, it does appear to be very think when compared to the other gaskets used. (Is it obvious that I am getting carried away by the excitement of finishing this, to the point that I'm forgetting things? Lesson learned).

Thanks for pointing that out V8.
