III. Primer Bulb and Choke
In Temperatures above 40°F (5°C):
Follow instructions in Section B.I. See "I. Primer Bulb Only"
instructions on page 10. See Table 4 on page 10.
In Temperatures below 40°F (5°C):
1. To avoid carbon monoxide poisoning, be sure engine is
outdoors in a well-ventilated area.
2. Move engine throttle control to “CHOKE” or “START”
position, if present (see equipment manufacturer’s
instructions). See Figures 25, 26 and 27.
3. When starting a cold engine, push primer bulb firmly 3
times, allowing primer bulb to return completely to orig-
inal position between pushes. See Figure 24 on page
11. Afterward, continue reading instructions below.
NOTES
Be sure to cover vent hole when pressing primer bulb. See
Figure 24 on page 11. Afterward, continue reading
instructions below.
Cooler temperatures may require pushing primer bulb firmly
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.
4. Operate equipment control to release engine brake or
clutch, if present (see equipment manufacturer’s
instructions). See Figure 25.
When pulling starter rope, the rope
can unexpectedly jerk back toward
engine causing serious injury. To avoid this risk, carefully
follow these instructions:
5. Grasp starter cord handle. See Figure 25.
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 engine throttle control to “FAST” position.
b. Next, move engine throttle control to desired speed
in “RUN” range.
NOTES
If engine starts but falters when
engine throttle control is
moved to “FAST” position:
a. Move engine throttle control back to “CHOKE”
position. See Figures 25, 26 and 27.
b. Next, move engine throttle control to “FAST”
position. See Figures 25, 26 and 27.
If engine dies after
engine throttle control is moved to “FAST”
position, repeat steps 2 thru 6 to restart engine.
7. If engine fires but does NOT continue to run, move engine
throttle control to “FAST” position and start engine.
8. If engine fails to start after 3 attempts in the “FAST”
position, move engine throttle control to “CHOKE”
position and start engine. See Figures 25, 26 and 27.
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.
