4. Loosen speed control bracket mounting screws.
Slide bracket forward or backward, until desired high
speed (RPM) is reached. Check speed with a
tachometer.
To increase high speed (RPM), move bracket toward
carburetor.
To decrease high speed (RPM), move bracket away
from carburetor.
5. Tighten speed control bracket mounting screws.
Recheck speed with a tachometer and readjust if
necessary.
Torque mounting screws as follows:
Into new hole – 11.0 N·m (95 in. lb.).
Into used hole – 7.5 N·m (65 in. lb.).
6. Adjust choke (see Choke Adjustment which follows).
Choke Adjustment
This procedure must follow High Speed Adjustment
just described. If not already completed, perform that
operation fi rst.
1. Turn choke adjusting screw out (counterclockwise),
until it no longer contacts choke lever.
2. Then turn it back in (clockwise), until it just makes
contact.
3. While observing choke link, move throttle control
lever to low idle (slow) position, then back to full
throttle (fast). Choke link should not move as throttle
moves through normal range. If it does, back
adjusting screw out until it no longer moves.
4. Move throttle control lever to choke position. Check
if choke has fully closed by placing your fi nger on
right side of lower end of choke lever/choke link and
applying gentle pressure towards carburetor. If
controls have been properly set, link should not
move.
SEPARATE THROTTLE AND CHOKE CONTROL
Some engines are equipped with separate throttle and
choke controls. This allows you to adjust choke and
throttle controls individually.
