RE: Need help IDing this engine..
Well, all of this doesnt matter anymore. The engine is junk. After the last run yesterday, the glow plug melted down and a chunk got between the piston and liner scoring the liner enough to lose over half of the compression it had. The engine will pop a few times but no more. Evidently it was a lost cause from the beginning. Its not worth putting a $50 piston and sleeve kit in it, IMO.
Thanks for your input, advice, and help. I was hopeful I could get it to run. As the Mythbusters say "Failure is ALWAYS an option"....
Thanks again.
