Preliminary Checks
Throttle Control Rod
Three preliminary checks must be made on the
mechanical governor before attempting any repair
adjustments. These are the governor oil level, drive
belt tension and the throttle control rod length.
Oil Level
Clean the body of the governor in the area of the fill
plug. Remove the oil level plug. If oil drips out, the
level is full. If oil doesn' t drip out, remove the oil full
plug and add 1 OW-30 or 1 OW-40 engine oil into the fill
hole until it starts dripping out of the oil level hole.
Install the oil level and oil fill plugs.
1.
Manually move the governor throttle lever to the
maximum open throttle with spring tension on the
governor.
2. Check the gap between the carburetor throttle
shaft lever and its maximum open position stop.
It should be l/32 to l/l 6 inch wide.
Belt Tension
3. If adjustment is necessary, loosen the control rod
ball joint locknuts, remove the rod from the
carburetor throttle lever and adjust the length of
the rod with the ball joints.
4. Install the throttle control rod on the carburetor
throttle lever and recheck the gap. Tighten the
locknuts.
Belt tension should be checked on a cold belt only.
1. Install the belt tension tool on the drive belt and
check the tension.
CAUTION: Be sure the throttle control rod is
properly installed with the long end at the
governor to prevent binding on the ignition wires.
