A. Engines with Electric Starters
Only one of the following two sections will apply to your
engine. See Table 3.
I. Engine With Primer Bulb
1. To avoid carbon monoxide poisoning, ensure engine is
outdoors in a well-ventilated area.
2. Be sure fuel valve (optional) is open and all switches
are on. See Figure 13.
3. Move Equipment Control (see equipment manufac-
turer’s instructions) or Engine Throttle Control to
“FAST” position or “HIGH” position. See Figures 14 and
15.
NOTE
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.
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 16.
NOTES
Cooler temperatures may require pushing primer bulb firmly
with your thumb 5 times.
DO NOT use primer to restart a warm engine after a short
shutdown. Doing so will flood the engine and may result in
equipment malfunction.
DO NOT operate an electric starter for more than 5 seconds
each attempt.
5. Push starter button or turn ignition switch key (see
equipment manufacturer’s instructions) to start engine.
6. When engine starts, release starter button or ignition
switch key.
7. If engine fails to start after 3 attempts, repeat steps 2
thru 6 and try again.
8. If engine does not start after following steps 1 thru 7,
contact your Authorized Tecumseh Servicing Dealer.
DO NOT attempt to start or troubleshoot this engine in
any other way.
