GOVERNOR
- ARM
The governor functions to maintain engine speed under changing load conditions and also acts as
a speed limiting device. The position of the throttle bracket determines speed range of the engine
(ar row indicates direction to decrease speed). The hole in the control disc into which the throttle
cable is inserted is also important as this establishes degree of governor control.
It
is a good idea to
permanently mark the exact position of the throttle bracket (scribe mark on crankcase) and also the
control disc hole in case linkage becomes disconnected or bushing or arm retaining nuts work loose.
If this is done, the governor can be quickly reset to original position.
Initial
This is made (with engine stopped) as follows: Loosen (do not remove) governor
arm
nut, grasp end of cross shaft in pliers and turn in counterclockwise direction until shaft
stops internally. Hold cross shaft in this position, then pull governor arm all the way away from car
buretor (with updraft type carburetor, lift arm as far as it will go) and retighten arm nut to complete
initial adjustment.
Cable Installation: If throttle cable becomes disconnected, use following procedure: Bend end of throttle
Wlre
as
in inset--if carelessly hooked or looped, wire will bind on control disc and cause
poor governor- action. Move throttle control handle to open position then insert wire into control disc
hole nearest to throttle bracket.
Speed
After readjusting governor, restart engine then move throttle to open position and
check top speed with hand tachometer. Maximum permissible speed for
K91
is
4000
RPM while for
most other models it is
3600
RPM. To decrease speed, loosen bushing nut and move throttle bracket
in
direction. Retighten bushing nut after adjustment (Do not overtighten--this could cause
binding of the cross shaft).
STORAGE INSTRUCTIONS
Use the following procedure to preserve engine before placing in storage.
Drain oil from crankcase (while hot) then flush with clean light oil. Refili crankcase after flushing.
Drain fuel from tank, sediment bowl and carburetor. Clean exterior of engine then spread light film
of oil over surfaces subject to corrosion (unpainted metal surfaces). Pour tablespoon of oil into spark
plug hole, turn engine over several times by hand then reinstall plug. Cover engine and store in dry
place.
