GOVERNOR
The
2
cylinder engines are equipped with centrifugal flyweight type mechanical governors which
are externally mounted at the rear of the gear cover and driven off the camshaft gear. The governors
are self
-
contained units except models prior to Serial
No.

which were
lubricated through an
external oil line which connects the engine lubrication system to the governor.
Governors are adjusted in the factory and further adjustment should not be needed unless linkage
becomes loose or disconnected. Always make sure linkage between governor and carburetor moves
freely.
If
governor
is
out of adjustment, engine speed will surge or hunt with changing load
or
speed
will drop considerably when a normal load
is
applied.
Governors also function to establish safe operat
-
ing speed limits
-
-
these must not be exceeded.
Although mechanical type governors are used on all two cylinder models, the
K662 governors are
different in design and therefore the
adjustment procedure varies slightly.
Governors are set at either
a constant speed setting or at a variable speed setting as determined by the engine application.
Make
sure the proper procedure is followed for the particular engine involved.

GOVERNORS
On the K482 and K532, the breaker points are mounted on the governor and are activated by the
breaker rod which rides on a
cam on the governor drive shaft.
For this reason, it is necessary to time
this governor to the engine. This is initially done during assembly of the engine and it will not have to
be done again unless governor has been
removed from the engine.
Installation and Timing:
Use
the following procedure to install and retime the governor to the engine:
1.
Uncover ignition timing sight hole on blower housing and also remove sight hole plug
located at top of gear cover.
2.
Turn engine over until Top Dead Center (DC) mark on flywheel is centered in ignition
timing sight hole.
3.
One of the teeth on the governor gear has a special timing bevel or deep chamfer
--
turn
gear so that this tooth is in the approximate 12 o'clock position or where it can
be
observed
in the gear cover sight hole after governor is installed (See Figure 5
-
1).
