MAINTAINING THE SPARK PLUG

The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
1. Remove spark plug boot.
2. Clean any dirt from around base of spark plug.
3. Remove spark plug using a 13/16 in. spark plug socket
(not provided).
4. Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
plugs are Torch E7RTC is NGK BPR6HS.
5. Measure plug gap. The correct gap is 0.028 − 0.031 in.
To widen gap, if necessary, carefully bend the ground
(top) electrode. To lessen gap, gently tap ground
electrode on a hard surface.
6. Seat spark plug in position; thread in by hand to prevent
cross-threading.
7. Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
