The enrichener system provides the engine with a
rich fuel charge for starting ease of a cold engine. The
system consists of an electrically operated
enrichener valve which is connected by hoses to the
carburetors.
Fuel is gravity fed to the valve from the float bowl of
the top carburetor via a hose. When the key (or choke
button) is pushed in (and held in) current is sent to the
valve causing it to open, which allows fuel to pass
thru. The fuel passes thru a hose and is supplied to
the engine via fittings located on top of the middle and
bottom carburetors. When the key (or choke button)
is released, the valve will return to the closed
position. The valve can be operated manually if valve
fails to operate electrically, refer to “Manual
Operation of Enrichener Valve,” following.
MANUAL OPERATION OF ENRICHENER VALVE
IMPORTANT: Use of enrichener if engine is warm
could result in engine flooding.
Squeeze primer bulb until bulb is firm. Press button
in on enrichener valve and hold approximately five
seconds. Release button. Start outboard.
