Spark Plug Model: Torch F6RTC
Only use the recommended spark plug or a spark plug with
the same temperature range. Using an improper spark plug,
an incorrect spark plug gap, or a dirty/fouled spark plug can
reduce engine performance and cause damage.
1. Stop engine and allow it to cool.
2. Remove spark plug wire from spark plug.
3. Remove the spark plug with a 13/16 in. (21 mm) deep
well socket.
4. Visually inspect the spark plug for cracks or damage. If
cracked, replace spark plug.
5. Clean carbon deposits. If excessive carbon build up, re
place spark plug.
6. Check that the gap of the spark plug is 0.028-0.031 in.
(0.7-0.8 mm). (Figure 18)
7. Re-insert the spark plug and tighten to 18-22 foot-pounds
(25-30 Nm).
8. Reattach spark plug wire to spark plug.
