5.Move engine speed control to “FAST” position. See Figures 21 and 22.

6.Set choke control to “FULL CHOKE” position (see equipment manufacturer’s instructions). See Figure 24 on page 12. Afterward, continue reading instructions below.

7.Hold the primer bulb in for one full second each time you press it. See Figure 23.

Make sure you cover vent hole with your thumb.

Repeat twice for a total of three primes.

NOTES

DO NOT operate an electric starter for more than 5 seconds each attempt.

DO NOT use primer bulb to restart a warm engine after a short shutdown. Doing so will flood the engine and may result in equipment malfunction.

If restarting a warm engine after a short shutdown, move engine speed control to “FAST” position and move choke control to “NO CHOKE” position. See Figures 21, 22 and 24. Afterward, continue reading instructions below.

8.Push starter button or turn ignition switch key, (see equipment manufacturer’s instructions), to start engine. See "C. Check the Following Items" instructions on page 6. Afterward, continue reading instructions below.

NOTE

If engine fails to start after 3 attempts repeat steps 1 thru 8.

9.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 Figure 24 on page 12. Afterward, continue reading instructions below.

c.Next, move choke control to “NO CHOKE” position.

10.Move engine speed control to desired speed in “RUN” range. See Figures 21 and 22.

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.

b.Next, move choke control to “1/2 CHOKE” position 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 5 thru 10 to restart engine.

11.If engine fires but does not continue to run, move choke control to “NO CHOKE” position and start engine. See Figure 24 on page 12. Afterward, continue reading instructions.
