CLEAN/REPLACE SPARK PLUG
CAUTION: Disconnect spark plug wire
from spark plug and keep wire away from
spark plug.
Change the spark plug every 100 hours of operation or
once each year, whichever comes first. This will help
your engine to start easier and run better. Replace with
champion J-19LM or equivalent type spark plug. Set the
spark plug gap to 0.030 inch (0.76mm).
If you think your carburetor needs adjusting, see your
nearest Sears Service dealer. Engine performance may
be affected above 4,000 feet in altitude. To improve
engine performance, see your nearest Sears Service
dealer.

immediately clean the nozzle with the kit included with
