Here is an engine that a neighbor gave me. At first I thought that it was a compressor made into an engine. Now I don't think so. If anybody knows what this is or has seen one like it or would just like to comment on it, please e-mail me! Thanks, Josh  holmesjsh@hotmail.com

Here is a view of the carberator. It is evidently set up for natural gas.  (notice the natural gas valve in the front and the priming cup in the rear.

ENGINE SPECS Bore - 2 1/2" Stroke - 2 9/16" Flywheel diameter - 6 3/8" Engine Height - 13 1/2"

Here are a couple of more views of the engine. The large pipe running from the crank case to the cylender is the intake port. Notice too that the cylinder actually is threaded and screws onto the crank case

Aside from the fact that the cylinder is cast with a water jacket, here are a couple of other things that make me believe that this is not a compressor conversion.  Notice that the piston has a deflector cast into it to deflect intake gases from being shot out the exhaust ports.  The other picture is a rather poor picture of the point mechanism. In real life it looks very factory built.
