necessary adjustment should be made by your Power Products Distributor listed at
the back of this manual. The adjusting procedure requires the use of tools which
are not readily available to consumers

Governors - Mechanical

WARNING: BEFORE PERFORMING ANY SERVICE OR MAINTENANCE TO
THE MECHANICAL GOVERNOR THE ENGINE MUST BE TURNED OFF AND
HAVE COME TO A COMPLETE STOP: ANY REMOTE START MUST BE
DISABLED AND LOCKED OUT.
Lubrication
Clean the body of the governor in the area of the fill plug. Check the oil lever by
slowly removing the oil level plug. If oil drips out, the oil level is full. If oil doesn't
drip out, slowly add engine oil into the oil fill hole. As soon as it begins dripping out
the oil level hole, insert the plug.
At the specified intervals, apply an appropriate lubricant, such as Lubriplate
(COAZ-19584-A) at the pivot points of the throttle, governor and choke linkage.
NOTE: Before making any governor adjustments, check the governor drive belt
tension with a belt tension gauge. -- Refer to "Check Condition of Ancillary Drive
Belts" on page 30.
Linkage Adjustment
The first adjustment is the governor-to-carburetor control rod adjustment. With the
control rod connected, manually move the governor throttle lever to the maximum
open throttle position. Check that the carburetor throttle shaft lever is set from 1/32
to 1/16 of an inch from its maximum open position stop. If necessary adjust length
of the control rod to obtain the setting.
High Speed Adjustment
1. Attach a tachometer to the engine suitable for Distributorless Ignition System.
2. Disengage any engine load and run the engine until it reaches normal operating
temperature.
3. Slowly increase the throttle to maximum no load engine speed.
4. Check engine RPM to determine if RPM is low or high.
5. Decrease throttle back to idle.
