Choke Adjustment
This procedure must follow the "High Idle Speed
Adjustment" just described. If not already completed,
perform that operation fi rst.
1. Turn the choke adjusting screw out
(counterclockwise), until it no longer contacts the
choke lever. Then turn it back
in (clockwise), until
it just makes contact.
2. While observing the choke link, move the throttle
control lever to the low idle (slow) position, then
back to full throttle (fast). The choke link should
not move as the throttle moves through the
normal range. If it does, back the adjusting screw
out until it no longer moves.
3. Move the throttle control lever to the choke
position. Check if the choke has fully closed by
placing your fi nger behind (right side) the link
loop and applying pressure toward the carburetor.
If the controls have been properly set, the link
should not move.
Sensitivity Adjustment
Governor sensitivity is adjusted by repositioning the
governor spring in the holes in the governor arm.
If speed surging occurs with a change in load, the
governor is set too sensitive. If a big drop in speed
occurs when normal load is applied, the governor
should be set for greater sensitivity.
The position of the governor spring in the governor
arm depends on the high idle, no load speed setting
(see Figure 5-23):
If the high idle, no load speed is 3600 RPM or less
-
use the #2 hole (count outward from cross shaft).
If the high idle speed is greater than 3600 RPM -
use the #3 hole (count outward from cross shaft).

Speed Control Bracket Service
The only serviceable components of the speed control
bracket assembly are the choke adjusting screw and
spring, choke return spring, and throttle cable clamp
and screw. Install the choke return spring as shown.
See Figure 5-24.
Replace the assembly if other parts are worn or
damaged.

Separate Throttle and Choke Control
Some engines are equipped with separate throttle and
choke controls. This allows you to adjust the choke
and throttle controls individually.
Install Separate Control Cables (See Figure 5-25).
Throttle Control
1. Loosen the 2-cable clamp screws on the engine
control plate.
