Readers' Engine Questions

| June/July 2002

A Brief Word

37/6/6: Homelite Generator See the photos of a Homelite Generator, Model HRUA, 115 volts, 13.1 amps, 1,500 watts, 60-cycle, s/n 12V11817. It is a 2-cycle outfit of about 2 HP. There is an insulated cover over the spark plug wire and a vacuum line to pull fumes out of the gas tank. It has olive drab paint underneath. I have been told it was a Navy issue in the early 1940s or an auxiliary power on W.W. II bombers. Any information on this unit would be appreciated. Ray Gray, 2135 Little Valley Road, Sevierville, TN 37862, or via e-mail at:

37/6/7: Unidentified Garden Tractor I acquired the garden tractor shown in the photo from a trash heap. No engine or belts were left and I replaced the one large pulley. So far I have no clue as to who built this unit. Any help would be appreciated. Bob Rose, 51 Simcoe Street, Oyster Bay, NY 11711.

37/6/8: Columbia Engine Q: We are trying to find information, especially concerning carburetion on 2-port/2-cycle kerosene engines. In particular we are working on a Columbia engine made in Detroit about 1911. This machine has a 5--inch bore and stroke (about 7 HP). Any information would be greatly appreciated. Doug Leighton, 3806 - 254th Street, Aldergrove, BC V4W 2R3 Canada.

A: Carburetion problems on early 2-cycle engines can present some difficult problems. Sometimes an engine that simply will not run smoothly under a load will settle right down with as little as holding a grease wiper against the flywheel. Part of the problem seems to be that early two-cycle engines were designed to work under load, and so no thought was given to smooth running when idle. With hopes of retiring soon, perhaps we'll finally have the time to compile our magneto and carburetor book, pulling together information from the mountain of literature we've acquired over the past 40-plus years. We've delayed doing so mainly because this is a project that will require a constant rain of thought for at least several weeks as we attempt to compile this book. We learned long ago that to attempt a project like this while under constant interruptions is completely frustrating ... it takes ye olde Reflector more time to figure out what happened in the previous research session than can be accomplished when we return to it. Meanwhile, if anyone can offer some suggestions on 2-cycle carburetion, please contact Mr. Leighton.

37/6/9: Empire Engine I am looking for information on an Empire engine made for Cockshutt Plow Co., Brantford, Ontario. It is 1- HP, s/n C111728. Any information would be appreciated. Chuck Baldwin, 2910 Jane Court NE, Albuquerque, NM 87112.

37/6/10: Unidentified Engine From the adjacent photos, can anyone tell me the make and model of the engine shown here? The engine was found in Colorado in the basement of a farm granary. I thought it might be a Fairbanks-Morse Type H, but the only thing that matches is the fuel pump. Any help would be greatly appreciated. Ken Lindblad, 11565 WCR76, Windsor, CO 80550.
