MAINTENANCE AND ADJUSTMENT
A breather passage is
incorporated in the tank cap.
If the breather passage is
clogged, the fuel will not flow
into the carburetor, causing
problems with starting or running
the engine. Check and clean
the breather passage before
operation. At the same time,
make sure that the base of the
breather assembly is fitted firmly
into the groove inside the tank
cap as shown.
