GOVERNOR
Q: How does the governor work?
A: Much maligned but seldom a problem, the system is a simple mechanical centrifugal fly weight device. On the
Honda engine, the mechanism runs off the camshaft or the crankshaft. Simple weights move a disc that in turn levers
an “L” shaped shaft.
The governor arm moves the carburetor throttle blade in direct
relation to engine speed; nothing more. It does not compensate for
engine load. When the engine RPM reaches a factory high setting,
the unit will retard the throttle setting automatically. At this point, the
engine surges as the governor cuts back the throttle yet the throttle
position demands more speed. Depending on how fast the engine is
turning, the governor weights will not kick up the spool as high. The
slower the engine is turning, the lower the spool sits on its shaft.
Now that we know that the governor closes the throttle, what opens
it? The governor spring is attached to the throttle lever, then to
governor arm, so the spring actually opens the throttle. If you did not
have a governor, the governor spring would pull the throttle shaft
all the way open and keep it there. A 5 HP small engine with the
throttle all the way open without a governor is capable of turning
around 6,000 RPM. The object of the governor is to oppose the work
of the governor spring and give you the safe, governed speed.
Rarely does the governor need adjustment. Most issues are the result
of worn linkage rods or springs.
Q: I have erratic idle speed but the carburetor checks OK.
A: Wear in the governor rod and spring will result in slightly
excessive movement of the rod. This will cause the idle speed to
“hunt.” Always keep the linkage slack in the governor system to a
minimum. Should the arm become worn and need to be replaced,
always scribe a mark on the governor shaft at a point where the new
part can be sure to be installed at the identical position of the old
arm; follow instructions in the Honda engine service manual should
adjustment be necessary.
seat. (Follow the instructions included with the valve grinding
kit).
Excessive carbon can also cause loss of performance and
increases in spark plug failure.
NOTE: It takes quite a bit of run time for this build-up to occur
in engines used on go-karts. Field reports indicate that a yearly
carbon removal is sufficient. A word to the wise: buy gaskets
and supplies for this job over the summer so you will have
them on hand during the off-season when you need them (and
GMs are reluctant to spend money).
