SPARK PLUG
Replace annually or every 100 above hours of operation.
Always replace with the same spark plug that came in the
engine and check gap before installing. Spark plug gap is
0.030”. Poor spark will also occur if spark plug wire does not
fit firmly on spark plug. If this happens, reform the terminal
to fit firmly on spark plug tip.
CARBON CANISTER
Designed to collect, store, and dispose of fuel vapors
created in the fuel tank/fuel system. The canister should last
the life of the unit as long as it stays dry.
