We just picked up this little gem. Has anyone come across this name before?

The water jacket cans are cast brass. The only thing keeping the two separate crankcases in alignment is the crank and the base mounts. We do have the bypass port inspection covers, but the ignition, pump, manifolds, etc. are missing.

Could it be that the manifolds also played a part in keeping the engine bits aligned?

Miro you are most likely correct.

On multiple cylinder engines with cylinders that bolt to the crankcase you need to install the cylinders and just snug down the cylinder bolts. Then torque the manifold bolts. Then torque the cylinder bolts. This way the manifold and everything else is aligned.

Too bad they don't have the manifold - but then again, maybe they copied something somewhere that just might show up.

Thanks guys. A manifold would definitely help keep things in line. I'm used to seeing the base (below the crank) as one casting or a significant connection between the cylinders (St.Lawrence). When this engine isn't bolted down, the two cylinders can rotate on the crankshaft independently.

There may have been a sturdy frame that it sat on at one time with dowels to line it up. There is an extra (third) hole in each base flange that may have been for a dowel.

Thanks again,
Blair
