39/7/1: Briggs Model Y Q: At a recent engine show I bought an engine I have always wanted - it had the kick-start and small, square gas tank mounted on the base. It might have been made in the Depression days to replace the Maytag washer engines. The nameplate gives this information: Type 60083, Model Y, serial no. 164798. 'Always give above information when writing about this motor or parts for it. We recommend Cross Country or Corona Oil (SAE 20) Summer and Winter. Sears, Roebuck & Co., the World's Largest Store.' Not surprisingly, our local Sears doesn't service anything that old.

In cleaning the engine, I found a Briggs & Stratton logo showing through a coat of black paint on the air housing. I cleaned the gas tank, check valve, screen, fuel line and freed the stuck accelerator plunger, which is connected to the air vane governor. I got a tickle from the spark plug wire when I moved the flywheel.

This engine has an extended shaft under the pulley. That shaft and the left-hand screw hold the kick-start gear onto the main crankshaft. That starting gear was in some way connected to a broken spring (original or home made?), which was under the tubular housing bolted together with the flywheel shaft. The spring that was there did not work. Looking at the broken pieces of the spring, I don't understand how the gear would activate the fly wheel/crankshaft and release when the engine started, and the kick lever returned.

I would like to talk or correspond with anyone who has knowledge of this engine and/or a parts engine with parts to make this engine work. Rob Maulsby, 416 Green Acres Drive, Huntsville, AL 35805-2527; (256) 837-4984.

A: The 1/2 HP Briggs & Stratton Model Y was designed for washing machine applications and was a fairly popular engine in its day. The Model Y was offered from 1931 to 1940, and according to serial number data on the Antique Small Engine Collectors Club Web site (, your engine was built in June 1935. We're hoping someone out there in engine land can help you sort out the kick-start mechanism, which is unique to that model.

39/7/2: Mystery Marine Engine Does anyone know what make this three-port, two-cycle engine is? John J. Wohlfeil, 190 County Road 550, Marquette, MI 49855-9704; (906) 345-0013; (248) 681-0808.
