II. Independent Speed and Choke Controls

1. To avoid carbon monoxide poisoning, make sure

engine is outdoors in a well-ventilated area.

2. Move engine speed control to “FAST” position

and set

choke control to “FULL CHOKE” position

(see equip-

ment manufacturer’s instructions). See Figures 14, 16 ,
17 and 18.

NOTES

Generator and Water Pump applications may have the
choke lever mounted on the engine. See Figure 18.

If restarting a warm engine after a short shutdown, move
Speed Control to “FAST” position and move Choke Control
to “NO CHOKE” position.

When pulling starter rope, the rope
can unexpectedly jerk back toward

engine causing serious injury. To avoid this risk, carefully
follow these instructions:
3. Grasp starter cord handle. See Figure 15.

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.

If engine fails after 3 pulls repeat steps 2 thru 3.

4. When engine starts:

a. Move choke control to “1/2 CHOKE” position until

engine runs smoothly.

b. Next, move control to “NO CHOKE” position.

5. Move speed control to desired speed in “RUN” range.

NOTES

If engine starts but falters when choke is moved to “NO
CHOKE” position:

a. Momentarily move choke control back to “FULL

CHOKE” position.

b. Next, move control to “1/2 CHOKE” position until

engine runs smoothly.

c. Finally, move control to “NO CHOKE “position.

If engine dies after 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

choke control to “NO CHOKE” position and pull starter
rope again.

7. If engine fails to start after 3 attempts in the “NO

CHOKE” position, move choke control to “FULL
CHOKE” position and pull starter rope 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.

VI. Stopping Your Engine and

Short-Term Storage

Stop engine according to equipment manufacturer’s
instructions.

To avoid unsupervised operation of
an engine, especially by children,

NEVER leave it unattended when it is running. Always turn
off the engine after use and remove ignition key, if provided.

Never store the engine with fuel in
the fuel tank inside a building with

potential sources of ignition such as hot water and space
heaters, clothes dryers, electric motors, etc.
