WARNING
All safety precautions should be adhered to
when testing the primer bulb system. Fuel
should be directed into suitable container and all
flammable materials extinguished and sources
of spark turned off.
NOTE: The manual starting primer bulb is designed
to provide a rich fuel mixture to the engine during cold
start conditions. When the primer bulb is pressed in,
fuel is forced from the primer bulb into the intake
manifold via hose and fitting on the side of the man-
ifold. When the primer bulb is released , a suction is
created in the bulb and fuel is drawn into the bulb
though a hose from the carburetor float bowl. Remov-
ing the primer hose from the intake manifold and
pressing the primer bulb will determine if the primer
is working properly as fuel should be expelled from
the hose whenever the primer bulb is pressed.
