4.Saturate the precleaner with new engine oil. Squeeze out all excess oil.

5.Reinstall the precleaner over the paper element.

6.Reinstall the air cleaner cover. Secure cover with the cover retaining knob.

Air Filter Paper Element Service

1.Loosen the cover retaining knob and remove the cover.

2.Remove the precleaner from the paper element.

3.Remove the element cover nut, element cover, and paper element.

4.Do not wash the paper element or use pressurized air, as this will damage the element. Replace a dirty, bent, or damaged element with a new ele- ment. Handle new elements carefully; do not use if the sealing surfaces are bent or damaged.

5.When servicing the air cleaner, check the air clean- er base. Make sure it is secured and not bent or damaged. Also check the element cover for dam- age or improper fit. Replace all damaged air cleaner components.

NOTE: Before air cleaner reassembly make sure rub- ber seal is in position around stud. Inspect, making sure it is not damaged and seals with the element cover.

6.Reinstall the paper element, precleaner, element cover, element cover nut, and air cleaner cover. Secure cover with the cover retaining knob.

SPARK PLUG SERVICE

To ensure proper engine operation, the spark plugs must be properly gapped and free of deposits.

1.Remove the spark plug caps.

2.Clean any dirt from around the spark plug bases.

3.Use a plug wrench to remove the spark plugs.

WARNING

The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot.

------------------------------------------------------------------------

4.Visually inspect the spark plugs. Discard them if the insulator is cracked or chipped. Clean the spark plugs with a wire brush if they are to be reused.

5.Measure the plug gap with a feeler gauge. Correct as necessary by bending the side electrode.

6.Check that the spark plug washer is in good condi- tion and thread the spark plug in by hand to pre- vent cross-threading.

7.After the spark plug is seated, tighten with a spark plug wrench to compress the washer.

-If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.

-If reinstalling a used spark plug, tighten 1/8 - 1/4 turn after the spark plug seats to compress the washer.
