Model Gasoline Engine Plans
We have for sale the following plan sets. All consist of details, assemblies and instructions on 8'' x 11" sheets. In addition, each set contains drawings covering construction of spark plug, fuel tank, piston rings, valve seating tool and ignition diagram, as well as optional construction choices. All are fabricated of aluminum, brass and steel stock without castings. However, the farm engines may look better with spoked flywheels and sources for these are given also. All of these are well proven designs, some having dozens of units successfully made by amateur machinists. All engines run on gasoline with spark ignition. The price of any single set of plans is $10.00 plus $3.00 postage.
