Clark W. Colby asks Gas Engine Magazine readers for help identifying a gas engine. 

I have heard your request for more material so I will try to help out. I will send articles in occasionally as I get time. This time though, I have a question. Has anyone ever seen or heard of an engine as I am about to describe? I bought it from a man named Zeb who collects antiques and want help identifying a gas engine.

The engine was made by the Ottawa Manufacturing Company in Ottawa, Kansas. The engine is rated at 7 hp @ 600 rpm. From here it becomes unusual. It is a 2 cylinder engine, both cylinders in-line. Both pistons are on the same crank-throw. Since it is a "four-cycle" engine, it fires once every revolution. It has an open crankcase and pushrod operated intake and exhaust valves which are in the head. It has one Wico magneto which trips every revolution and has two high voltage outputs. It also has a throttling governor and a reed instead of a choke. The valve seats are square and water hopper is removable. I would appreciate any information which any reader could supply.

I am 17 years old and have 30 gas engines and an I.H.C. regular tractor. I would be happy to answer any questions on identification or repair of any gas engines that any of you readers might have. I don't have one of everything, but don't have too many duplicates either, so I'll help to the best of my ability.
