CAUTION
DO NOT attempt to start the engine unless the pump
has previously been primed with water. Severe pump
damage will occur if pump has not been primed.
4. Place the choke lever (See Figure 10) in the OPEN
position if starting a warm engine or the temperature
is warm.

the starter grip briskly and smoothly for starting.

moved to the CLOSED position to start the engine,
gradually move the choke lever to the OPEN position
