Flywheel Forum

This engine has a 6-inch bore and 10-inch stroke, 42-inch
diameter flywheels, round connecting rod, and a 2-1/4-inch shaft
diameter with 5/8-inch keyway. The 3-bolt bearing caps have “436”
cast on them and the flywheels have drilled balance holes with the
number “131” cast on them. It has a Waterloo igniter bracket No.
303K8 and a Witry governor. The rocker arm has the number “59-12”
on it. The muffler is not original and the gas tank has been
replaced. There is no nameplate nor can I find anything to indicate
where one would have been. There is no serial number on the shaft
end or casting number on the base. I have been told that it has a
lot of Waterloo features but is not a true Waterloo-built engine.
Thank you for any information you can give to help with identifying
this engine. Sheldon Frankenfield, 2605 Canoga Road, Seneca Falls,
