|PowerHouse 4-Cycle Gas
"PowerHouse" engine is a long stroke design for medium to low speed
operation. By having a long stroke, it is capable driving a load such
as a generator or pump at a leisurely pace. It is made from bar stock
and was designed to be as easy to build as possible while retaining
good looks. The frame and base plate is from aluminum alloy plate. The
cylinder, piston and head are of cast iron bar stock; and the flywheel
is of mild steel. The engine is air cooled by fan (belt driven or
electric), although it will also operate without one. Spark
advance/retard is adjustable while the engine is running. The
carburetor is an easy to build type with adjustable speed control and
an air cleaner. The engine will run an hour or so on 2 ounces of fuel.
You will need a 6" lathe and a small milling machine with a 6" diameter
rotary table. This engine should be as easy for beginners to build as
any, and easier than most because the engine frame is so simple.
The model runs from 500 RPM idle to around 1,800 RPM or so wide open
and the sound is real nice with the right exhaust pipe at about 800 RPM.
The plans set consists of 16 sheets of quality laser printed CAD
drawings and 1 sheet of construction and assembly notes.

enjoy your plans very much, without a doubt they are the best "bar
stock" type plans I have ever seen." - Dave Otto (Boise, Idaho)
