While fiddling with my stash of old 1/2A and smaller engines I discovered that an OK Cub .049 head will screw into an old Space Bug cylinder. Is this a new discovery, or are you all yawning and saying, "So what else is new?" I don't know if anyone still uses the original small cylinders, but if so, with a little lathe work on combustion chamber volume, you've got a cheap head with replaceable plug.

The Geoff who came after the first one.
