7. If engine fires but does not continue to run, move

B. Engine With Variable Speed Control
NOTE
Some engines are equipped with a fixed speed control.
1. To avoid carbon monoxide poisoning, be sure engine is
outdoors in a well-ventilated area.
2. Move throttle control lever to “FAST” or “START”
position, if present (see equipment manufacturer’s
instructions). See Figure 15.
3. Move choke control on engine to “FULL CHOKE”
position. See Figures 11 and 12 on page 6. Afterward,
continue reading instructions below.
4. When starting a cold engine, push primer bulb firmly
with your thumb 3 times, allowing primer bulb to return
completely to original position between pushes. See
Figure 13.
NOTES
Cooler temperatures may require pushing primer bulb firmly
with your thumb 5 times.
DO NOT use choke or primer bulb to restart a warm engine
after a short shutdown. Doing so will flood the engine and
may result in equipment malfunction. See Figure 13.
When pulling starter rope, the rope
can unexpectedly jerk back toward
engine causing serious injury. To avoid this risk, carefully

a. Pull rope out slowly until you feel drag.
b. Without allowing the rope to retract, continue pulling
rope with one rapid full arm stroke.
c. Return rope slowly to original position.
NOTE
Following the instructions listed in the steps above avoids
potential damage to the recoil mechanism.
6. When engine starts:
a. Move choke control to “1/2 CHOKE” position until
engine runs smoothly.
b. Next, move choke control to “NO CHOKE” position.
c. Move throttle control lever to desired speed in “RUN”
