7 ADJUSTMENTS
7.1 Clutch Adjustment
Proper clutch adjust is very important. Minor adjustment, if needed, can be made by using the
links on the clutch cable chain only. However, the friction type clutch may need further
adjustments as the “V” belt wears. Adjust as follows:
1. Remove belt guard.
2. Loosen 4 engine mount bolts. Slide engine forward or
backwards as required.
3. Unhook clutch cable from load spring.
4. Push upward on idler pulley to take all slack from the
drive belt. Distance between the inside of belt at the
idler pulley should be approx. 4”
5. Ensure pulleys are aligned with a long straight edge.
6. Retighten engine mounting bolts (17-foot lbs. of torque).
7. Remove all the slack from clutch cable and hook spring in proper chain link providing little
to no tension to the clutch cable.
8. Check your adjustments by:
a. First insure that unit is secure on kickstand and drive wheel is off the ground.
b. Disconnect spark plug wire
c. Pull recoil starting rope and turn over engine.
d. The drive wheel should not turn. If it does repeat steps 2-6 for additional belt
slack.
e. Only if the unit is secure on kick stand and wheel does not turn when engine
recoil rope is pulled, reconnect the spark plug wire.
f. Check your adjustment by starting the engine, by referring to the Starting
Procedure step 6.6. The drive wheel should only spin when clutch lever is fully
engaged with the spring having some stretch. Adjust the clutch cable spring if
necessary to only turn drive wheel when compressing clutch lever.
7.2 Handle Height Adjustment
1. Handle height position may be adjusted by re-positioning the mounting hardware of the
handle brace lower frame mount. Both braces must use same height adjusting hole for
each side.
DANGER
To avoid possible serious bodily injury, when performing any adjustments, remove the spark plug wire
and place the wire away from the plug to prevent accidental starting.
