5. Replace the spark plug with the proper spark plug.
Consult the parts breakdown for the spark plug to
be used in the engine being serviced. The spark
plug air gap is .030''. Install spark plug in engine
and tighten to 15 foot pounds torque. If a torque
wrench isn't available, screw spark plug in as far as
possible, by hand, and use a spark plug wrench to
turn spark plug 1/8 to 1/4 turn further when reusing
spark plug, or 1/2 turn further if using a new spark
plug.
6. Make sure all ignition wires are free of abrasions,
breaks and are properly routed so they will not rub
on flywheel.
7. Properly reinstall the blower housing, gas tank, and
fuel lines, then properly check for spark as stated in
the ignition section of this manual.
8. Make sure all cables are adjusted for proper
operation.
