FUEL PUMP. - A dlaphragm type fuel pump is usect. If fuel does not
reach the carburetor, check the fu~l pump before dis-
.mantling it. The pump can be checked by disconnecting the fuel line at
the carburetor, cranking the'engine slowly by hand, and observing whe-
ther fuel comes from the line at the carburetor. If there is enough
fuel in
the tank, and the line between the tank and the pump .is open but
,the pump
fails, repair or replace it. Failure of the pump is usually
due to a leaking diaphragm, valve or valve gasket, a weak or broken
'spring, or wear in the drive linkage. If the operator chooses to repair
the pump rather than install a new one, the use of a complete repair
kit is recommended.
ALWAYS RETURN THE HAND PRIMING LEVERALL-THE-WAY IN-
WARD so that the priming lever does not prevent the normal operation
of the pump. If the fuel pump rocker arm is being lifted by the cam-
shaft, the engine must be cranked 1 revolution before the priming lever
will be effective.
Rotating the diaphragm 1/4 turn will dtsengagethe drive link ..
,!Diluted oil indicates a faulty fuel pump.
,GASKETS. - Always use new gaskets when replacing any part that re-
quires a gasket. Thoroughly clean the surface that the gas-
ket contacts before installing the gas):{et.
TESTING IGNITION COIL. - A
6-volt tester may be used to test the
, ignition coil. To avoid burning out the coil,
do not use a 12-volt tester and do not leave coil on tester over 15 or 20
minutes.
