Enrichener System
(Electric Start Models)
The enrichener system provides the engine with ex-
tra fuel charge for ease of starting cold engine. The
system consists of an electrically operated enrichen-
er valve which is connected by a hose to the intake
manifold.
The enrichener system is pressurized by squeezing
the fuel line primer bulb or by the fuel pump when the
engine is being cranked. When the ignition key is
turned to the “on” position and pushed in (and held
in), current is sent to the valve causing it to open,
which allows pressurized fuel to pass thru a hose to
a fitting on the intake manifold. When the key (or
choke button) is released, the valve will return to the
closed position. The valve can be operated manually
by pressing and holding button located at bottom of
valve
. The small hose connected to fitting at the base
of the oil pump relieves excess crankcase pressure
at the oil pump drive.
