FUEL
SYSTEM
Always use a high quality brand of leaded or
unleaded gasoline free from dirt and water. Some
poorer grades of gasoline contain gum which
deposits on valve stems, piston rings, and in the
various small passages in the carburetor. This can
cause serious engine operating problems.
Use
gasoline with an octane rating of at least
86.
Fuel with a
low
octane rating will cause detonation. If
operation
is
continued under this condition, severe
damage will result to the engine. Teledyne Total
Power recommends fuels with no more than
10
per-
cent alcohol content.
GOVERNOR
OPERATION
The governor is mounted on the governor gear in the
crankcase cover.
As
the engine speed increases, the
centrifugal force in the flyweights acts against the
governor spring and closes the carburetor throttle to
a point where the engine speed will be maintained
practically constant under varying load conditions.
