Choke Adjustment
This procedure must follow the High Speed
Adjustment just described. If not already completed,
perform that operation first.
1. Turn the choke adjusting screw out
(counterclockwise), until it no longer contacts the
choke lever.
2. Then turn it back in (clockwise), until it just
makes contact.
3. While observing the choke link, move the throle
control lever to the low idle (slow) position, then
back to full throle (fast). The choke link should
not move as the throle moves through the
normal range. If it does, back the adjusting screw
out until it no longer moves.
4. Move the throle control lever to the choke
position. Check if the choke has fully closed by
placing your finger on the right side of the lower
end of the choke lever/choke link and applying
gentle pressure towards the carburetor. If the
controls have been properly set, the link should
not move.
Separate Throttle and Choke Control
Some engines are equipped with separate throle and
choke controls. This allows you to adjust the choke
and throle controls individually.
Install Separate Control Cables
Throttle Control Installation
1. Loosen the two cable clamp screws on the speed
control bracket assembly. See Figure 5-19.
2. Move the application throle control lever to the
maximum full (fast) throle position, and then
move it back 3/16" or 4.75 mm. Insert the cable
boden wire into the throle control lever on the
control plate.
3. Position the throle cable under the cable clamp.
Figure 5-18. Adjusting High Speed (RPM).
To increase the high speed (RPM), move the
bracket toward the carburetor.
To decrease the high speed (RPM), move the
bracket away from the carburetor.
5. Tighten the speed control bracket mounting
screws. Recheck the speed with a tachometer and
readjust if necessary.
Torque the mounting screws as follows:
Into new as-cast hole – 11.0 N·m (95 in. lb.).
Into used hole – 7.5 N·m (65 in. lb.).
6. Adjust the choke (see Choke Adjustment which
follows).
Later Models: Later models utilize a new design
control assembly, identified by two opposing
alignment holes (close to the throle lever pivot),
instead of one. Based upon the intended high
speed (RPM) seing, throle cable adjustment
must be made matching the hole in the control
lever with the appropriate alignment hole. Use
the lower (le side) hole for high-speed seings
3000 RPM and above. Use the upper (right side)
hole for high-speed seings less than 3000 RPM.
Move the throle lever to align the hole in the
lever with the appropriate hole in the control
bracket. Insert a pencil or a 6.35 mm (1/4 in) drill
bit to hold in position. See Figure 5-16.
4. Loosen the speed control bracket mounting
screws. Slide the bracket forward or backward,
until the desired high speed (RPM) is reached.
See Figure 5-18. Check the speed with a
tachometer.
