FUEL SYSTEMS - 3B-1390-817643R1 DECEMBER 1996
Maintenance
Periodically check fuel line and primer bulb for cracks,
breaks, restrictions or chafing. Check all fuel line connec-
tions for tightness. All fuel line connections must be
clamped securely.
Primer bulb assembly has 2 check valves: Fuel inlet (to-
ward tank) and a fuel outlet (toward engine).
The fuel inlet valve allows fuel to fill primer bulb but closes
to prevent fuel from returning to tank when bulb is
squeezed. The fuel outlet valve opens when primer bulb is
squeezed to allow fuel flow to carburetor, but closes as bulb
is released to prevent fuel from returning to primer bulb.
