MAINTENANCE

adjusting valve-to-rocker arm clearance­

See Figures 25 - 27.

Inspect the valve-to-rocker arm clearance after every

25hours of operation. This should be done in a clean, dust- free environment.

NOTE: This procedure requires partial disassembly of the engine. If you are unsure if you are qualified to perform this operation, take the unit to an authorized service center.

Stop the engine and disconnect the spark plug wire. Allow the engine to cool completely before proceeding.

Remove the screw from the top engine cover. Remove engine cover and set aside.

Using a Torx screwdriver, remove the screw from the rocker arm cover. Remove the cover and set aside.

Align rocker arms by pulling the recoil starter grip just until the deep hole in the belt pulley is located at the bottom as shown in figure 24.

Place the feeler gauge under each rocker arm and mea- sure the gap as shown in figure 25. The gap should be between .0045 in. and .005 in. for both rocker arms.

NOTE: Use a standard automotive .005 in. feeler gauge. The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance but without binding.

If the valve clearance is not .005 in., the clearance should be adjusted as follows:

While holding a wrench on the flats of the adjusting nut with one hand, loosen the retaining nut with a second wrench as shown in figure 26.

Rotate the adjusting nut until it touches the feeler gauge. Once the gap setting is correct, hold the wrench on the flats of the adjusting nut and retighten the retaining nut securely.

Adjust the second rocker arm, if necessary.

Replace the rocker arm cover and screw; tighten

securely­ .

Replace the top engine cover and screw; tighten

securely­ .

WARNING:

Ensure all engine cover and all engine parts are completely and properly reassembled before starting engine. Failure to correctly reassemble engine may result in serious injury or property damage.
