3. Remove the spark plug; then attach the high tension

lead to the plug and ground the plug on the cylinder

head well away from the spark plug hole.

4. Attach the Compression Tester Kit (p/n 0444-213).

NOTE: The engine must be warm and the battery

must be fully charged for this test.

5. While holding the throttle lever in the full-open posi-

tion, crank the engine over with the electric starter

until the gauge shows a peak reading (five to 10

compression strokes).

NOTE: Compression should be within a range of

195-230 psi in the full-open throttle position.

6. If compression is abnormally low, inspect the follow-

ing items.

A. Verify starter cranks engine over.

B. Gauge is functioning properly.

C. Throttle lever in the full-open position.

7. Pour 29.5 ml (1 fl oz) of oil into the spark plug hole,

reattach the gauge, and retest compression.

8. If compression is now evident, service the top end

(see Engine/Transmission - Servicing Top-Side

Components).

Spark Plug

A light brown insulator indicates the plug and air/fuel ratio

are correct. A white or dark insulator indicates that the

engine may need to be serviced or the carburetor may need

to be adjusted. To maintain a hot, strong spark, keep the

plug free of carbon.

ATV-0051

Adjust the gap to 0.6-0.7 mm (0.024-0.028 in.) for proper

ignition. Use a feeler gauge to check the gap.

ATV-0052A

A new spark plug should be tightened 1/2 turn once the

washer contacts the cylinder head. A used spark plug

should be tightened 1/8 - 1/4 turn once the washer con-

tacts the cylinder head.

Muffler/Spark Arrester

To clean the arrester, use the following procedure.

1. Remove the cap screw (1) securing the spark arrester

assembly (2) to the rear of the muffler. Account for a

gasket.

KM139A

2. Clean the screen (3) with a brush and parts-cleaning

solvent. Dry with compressed air. If the screen has

any holes or tears, it must be replaced.

! WARNING

Always wear safety glasses when using compressed
air.

CAUTION

Before removing the spark plug, be sure to clean the
area around the spark plug. Dirt could enter engine
when removing or installing the spark plug.

! WARNING

Before removing the muffler/spark arrester, wait for it to
cool to avoid burns.
