Starting
1. Move throttle (Fig. 15) to FAST.
2. Open fuel shut-off valve below fuel tank (Fig. 14).
3. Rotate choke (Fig. 15) to full choke position.
4. Insert ignition key (Fig. 15).
5. Cover hole in center of primer with thumb and push
primer slowly three times. DO NOT PRIME IF THE
ENGINE HAS BEEN RUNNING AND IS HOT.
Note: Excessive priming may cause flooding of engine
and failure to start.
6. Grasp recoil starter handle (Fig. 15) and pull it out
slowly until positive engagement results; then pull
vigorously to start the engine. Keep firm grip on
starter handle and return the rope slowly.
Note: If engine does not start or if temperature is
–10
_
F (–23
_
C) or below, additional priming may be
required. After each additional prime, try to start the
engine before priming again.
7. After engine starts, immediately rotate choke (Fig. 15)
to 3/4 position. As engine warms up, rotate choke to
1/2 position; then to OFF position. If engine falters,
return choke to 1/2 position. When engine warms
sufficiently, rotate choke to OFF position.
