Re: Thermal Hopper Question.
Head looks correct as does backplate, externally the cylinder looks correct. Should be dual bypass, tapered grind with SPI.
Front end /crankcase is typical of most early cox engines. The front acorn nut has been ground down or damaged.

Re: Thermal Hopper Question.
Thanks Cribbs, it looked legit to me as well but wasn't to sure about the ridges on the side of the crankcase next to the backplate. I did purchase it so have to wait to inspect it more.
Thanks Canso07.

Re: Thermal Hopper Question.
I think what you are seeing is just a casting flaw.
