7. Determine the condition of the spark plugs by check-
ing the gap with a feeler gauge. The gap must be
within the range indicated in the illustration.
• If both spark plugs are within the range, reinstall
them.
• If the gap on either spark plug is not within the
correct range, replace both spark plugs with new
ones. Always replace spark plugs in pairs.

spark plugs. Install the spark plugs and tighten to
16.2 - 23.6 ft.lb (22 - 32 Nm).

will be expelled through the spark
plug opening and could be ignited

in a fire.

To properly prepare for a compression test:
1.
Lift the entire vehicle. See THE SAFETY section for
the procedure to lift the vehicle.
2. Place the shifter in the P (park) position.
3. Run the engine until it reaches normal operating
temperature and then turn it off.
4. Disconnect the fuel line from the fuel tank and plug
the line to prevent contamination. Run the engine
until the fuel is depleted.
5. Remove the air filter to eliminate the possibility of a
restricted air passage.
6. A good, well charged battery should be used. A weak
battery may not provide the correct cranking speed.
7. Install a compression tester. Follow the tester manu-
facturer’s instructions for use.
8. Turn the engine over. Make sure the throttle is fully
open to let air in. Make sure the reading is normal
per the engine manual compression specifications. If
the compression reading is low, check for correct
valve adjustment. If the valves are properly adjusted,
the cause may be valve damage or a head gasket
leak, etc. See Textron Motors Repair Manual
