SPARK PLUG MAINTENANCE AND REPLACEMENT

Refer to the Specifications for spark plug type and gap specifications. Check and clean spark plugs every 200 hours. Replace plugs every 500 hours.

To prevent cross threading the spark plug, always thread it in by hand until it seats. If the spark plug is being reused, turn it with a wrench and additional 1/4 turn. If the spark plug is new, turn it an additional 3/8 to 1/2 turn. If you have a torque wrench, tighten a new spark plug to 11.8-14.7 N-m (120-150 Kg/cm) (8.7-10.9 ft/lb).

CHECKING BATTERIES

Every 50 hours or once a month check the fluid level of the battery. Refill with distilled water if levels are low.

To adjust the speed control solenoid:

1Run the engine with no load until the engine control times out (about 15 seconds) and energizes the solenoid.

2Adjust engine to 2200 RPM by loosening the two slotted screws retaining the solenoid.

3Slide solenoid forward to increase the speed, or backwards to decrease the speed.

4Retighten the two screws.

Following reassembly of either the carburetor or intake manifold, re- align the governor arm on the governor shaft BEFORE making speed adjustments to compensate for the slightly different alignment of parts.
