Checking Fuel System; Inspecting Fuel Filter - PowerTec 40Hp Owner's Manual

Maitenance
Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)
When fitting the plug, always clean the gas-
ket surface and use a new gasket. Wipe off
any dirt from the threads and screw in the
spark plug to the correct torque.
Spark plug torque:
25.0 Nm (18.4 ft-lb) (2.55 kgf-m)
NOTE:
If a torque-wrench is not available when you
are fitting a spark plug, a good estimate of
the correct torque is 1/4 to 1/2 a turn past fin-
ger-tight. Have the spark plug adjusted to the
correct torque as soon as possible with a
torque-wrench.
