CLEANING OF VALVE PORTS­
EXHAUST
The only service required to the valve
ports is an occasional cleaning to remove
carbon deposits. Remove
muffler
assembly
from engine (see Fig. No.8) which will
expose the exhaust valve ports and clean
with suit
able
instrument capable of scrap­
ing and removing the carbon deposits
within these
ports,
The engine should be
turned over by hand until piston moves
below the POrt openings which will al­
low greater access for the cleaning of these
parts
.
(Care should be taken so as not to
damage or score the
porr when
cleaning.)

the
reed
valve in repairing
and servicing this assembly.
The reed valve
can
be visually checked
for leakage by looking into the intake port
side of the reed plate and if light is de­

seats on the reed plate
,
it
is the

recom­
mended that the reed
valve be
