CLEANING/REPLACING THE SPARK PLUG
See Figure 33.
NOTICE
ALWAYS use the Westinghouse OEM
or compatible non-resistor-type spark plug. Use of resis-
tor-type spark plug can result in rough idling, misfire, or
may prevent the engine from starting.
Be sure the spark is clean and properly gapped. To clean or replace
the spark plug:
l Turn the generator off and allow the engine to cool for 30 min-
utes.
l Place the generator on a level surface in a well-ventilated area.
l Remove the spark plug boot by firmly pulling the spark boot
directly away from the engine.
l Clean the area around the spark plug.
l Remove the spark plug with the included spark plug socket
wrench.
NOTICE
Never apply any side load or move the
spark plug laterally when removing the spark plug.
l Inspect the spark plug. Replace if electrodes are pitted, burned,
or the insulator is cracked. Only use a recommended replacement
plug.
l Measure the spark plug electrode gap with a wire-type feeler
gauge. If necessary, correct the gap by carefully bending the
side electrode.
Spark plug gap: 0.024 – 0.032 in. (0.60 – 0.80 mm)
l Carefully install the spark plug finger tight, then tighten as
additional 3/8 to 1/2 turn with the spark plug wrench.
l Install the spark plug boot.
CLEANING THE SPARK ARRESTOR
See Figure 34.
Inspect and clean the spark arrestor according to the figures
specified in the maintenance schedule or the engine manual
(if applicable). Failure to clean the spark arrestor will result in
degraded engine performance.
