CLEANING/REPLACING THE SPARK PLUG
See Figure 33.
NOTICE
ALWAYS use the Westinghouse OEM
or compatible non-resistor-type spark plug. Use of re-
sistor-type spark plug can result in rough idling, mis-
fire, or may prevent the engine from starting.
Make sure the spark is clean and properly gapped. To clean
or replace your spark plug:
l Turn the generator off and allow the engine to cool for
30 minutes.
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 recom-
mended 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.
