Unknown engine, strange carburetors and a little help with an old mystery
I have an old gas engine that I can't identify. It has a 5-inch bore, the serial number is 190576, the RPM is 425, and the horsepower is labled as 5E. It currently has a spark plug but I do not know if that is original equipment. I am interested in any information as well as any photos of this model of engine. Paul Stagg, P.O.

I found these very strange carburetors at a flea market. The U-shape has a butterfly plate in both ends of the tube and the mixture needle is in the bottom of the curve. The flange suggests it was bolted directly to a gas tank, although the center hole is threaded, so it may have had a pick-up tube or check valve here. Does anyone know what it would fit or better yet, does anyone have one of these engines for sale that needs a carb? Jim Koby, P.O. Box 177, Manilla, IN 46150.
I would like to submit the following information in regard to the mystery engine from the June 2006 issue of Gas Engine Magazine. Regarding the casting numbers on both the APLCO and Termaat & Monahan engines (1 4 H29), I have two Termaat & Monahan engines. One reads 2-1/2 4 H29 and the other 6 4 H29. I take the figures to mean 2-1/2 or 6 HP, 4-cycle, hopper cooled and 29 horizontal design.
I am also looking for a flywheel for the 6 HP with 64H19 scribed in the flywheel, as pictured. Don Selle, 140 Poplar St., Turtle Lake, WI 54889; (715) 986-2451.
A long time ago, Rusty Hopper mentioned in Modeler's Corner that the model he was building would be run on propane and the technical details would be described later. The details would likely have included the making and operation of a suitable valve or regulator scaled down for the model. Unfortunately, the series from RH stopped and the story was never completed.
Is there any other expert out there who would set out how best to run scale engines on propane? Norma McIntyre on behalf of Peter Dewar, Naim, Scotland.
