II. Engine With Choke
1. To avoid carbon monoxide poisoning, make sure
engine is outdoors in a well-ventilated area.
2. Be sure fuel valve (optional) is open and all switches
are on. See Figure 18.
3. Move Equipment Control (see equipment manufac-
turer’s instructions) or Engine Throttle Control to
“FAST” position or “HIGH” position and set Choke Con-
trol to “FULL” position. See Figures 17, 19, and 20.
NOTES
If restarting a warm engine after a short shutdown, move
Equipment Control to “FAST” position and Choke Control to
“NO CHOKE” position. See Figures 17, 19 and 20.
Some engines are equipped with an optional Spring Loaded
Throttle Control. This spring loaded control is used to
ensure the throttle will return to engine idle speed if it is
released or if the cable fails. The throttle control must be in
the idle position when starting engine.
DO NOT operate an electric starter for more than 5 seconds
each attempt.
4. Push starter button or turn ignition switch key (see
equipment manufacturer’s instructions) to start engine.
5. When engine starts:
a. Release starter button or ignition switch key.
b. Momentarily move Choke Control to “1/2 CHOKE”
position until engine runs smoothly. See Figures 17.
c. Next, move Choke Control to “NO CHOKE” position.
6. Move Engine Speed Control to desired speed in “RUN”
range. See Figures 19 and 20.
NOTES
If engine starts but falters when Choke Control is moved to
“NO CHOKE” position:
a. Momentarily move Choke Control back to “FULL
CHOKE” position. See Figure 17.
b. Next, move Choke Control to “1/2 CHOKE” until
engine runs smoothly.
c. Finally, move Choke Control to “NO CHOKE”
position.
If engine dies after Choke Control is moved to “NO CHOKE”
position repeat steps 2 thru 6 to restart engine.
7. If engine fires but does not continue to run, move
Choke Control to “NO CHOKE” position and start
engine.
8. If engine fails to start after 3 attempts in the “NO
CHOKE” position, move Choke Control to “FULL
CHOKE” position and start engine.
9. If engine does not start after following steps 1 thru 8,
contact your Authorized Tecumseh Servicing Dealer.
DO NOT attempt to start or troubleshoot this engine in
any other way.
