From the bucket-o-engines. Looks McCoyish, but that crankcase?!?
So -- anyone know what it is? Good for parts? Good engine, if I can mount it? How is that venturi held in?

Tim, thats a Testor's engine from the ready to fly plastic models that really never flew. The venturi is press fit in to the back of the case. Give it a good pull and a wiggle and there you will find the reed. Those engines were made in the cast metal and also plastic which was like a reinforced nylon. I did have a few that ran and the crank usually departed first. Ken

It seems to have a good cylinder/piston fit -- I'm thinking that if the cylinder fits my other Testors engines I make just keep it for parts.
Or maybe I'll go to the trouble of making a plywood saddle for it, and go fly it.
So they really made those with plastic crankcases? Jeesh -- how cheap can you get?
-
Tim, the glow head, starter parts, needle valve assembly, cylinder \piston will fit your wen-mac mccoy.

My "product engine" with metal crankcase was in a space ship looking plane. Here is the standalone Testors 8000 with the "plastic" crankcase. They came with the cylinder mounted to the side.

For those with the machine shop and engine design skills, it might be possible to redesign crankshaft timing and fuel intake opening using the solid crankshaft and then put it into a FRV Wen-McCoy block.

There's an engine design -- the Schroeder "Simple Single" -- out there that uses a Cox cylinder, piston and rod, and goes into a custom crank case with crank, etc. One could probably adapt it to this one.

No reason it couldn't be glow.
