outdoors in a well-ventilated area.
2. Move independent speed control to “FAST” position
and set independent choke control to “FULL CHOKE”
position (see equipment manufacturer’s instructions).
See Figures 9 thru 11 starting on page 6. Afterwards,
continue reading instructions below.
NOTES
Generator and Water Pump applications may have the
choke lever mounted on the engine.
See Figure 12.
If restarting a warm engine after a short shutdown, move
independent
speed control to “FAST” position and move
independent choke control to “NO CHOKE” position.
3. Push starter button or turn ignition switch key (see
equipment manufacturer’s instructions) to start engine.
NOTES
DO NOT operate an electric starter for more than 5 seconds
each attempt.
If engine fails to start after 3 attempts repeat steps 2 thru 3.
4. When engine starts:
a. Release starter button or ignition switch key.
b. Move independent choke control to “1/2 CHOKE”
position until engine runs smoothly.
c. Next, move independent choke control to
“NO CHOKE” position. See Figure 11.
5. Finally, move independent speed control to desired
speed in “RUN” range.
NOTES
If engine starts but falters when independent choke control
is moved to “NO CHOKE” position:
a. Momentarily move independent choke control back
to “FULL CHOKE” position.
b. Next, move independent choke control to
“1/2 CHOKE” position until engine runs smoothly.
c. Finally, move independent choke control to
“NO CHOKE” position.
If engine dies after independent choke control is moved to
“NO CHOKE” position, repeat steps 2 thru 5 to restart
engine.
6. If engine fires but does NOT continue to run, move
independent
choke control to “NO CHOKE” position
and start engine.
