FUEL SYSTEM AND GOVERNOR

The choke rod is part of the heat box assembly
mounted on the front of the carburetor.
See Figure 4.22.
NOTE: The choke rod can be bent slightly to facilitate
adjustment.
To adjust the choke rod:
1. Remove the choke knob and the engine shroud by
following the steps described in Chapter 3: Air Intake
Systems.
2. Rotate the choke knob shaft to verify full choke
movement.
See Figure 4.23.
3. If the choke plate does not open fully or close fully,
adjust the choke linkage.
NOTE: When adjusting the choke linkage, make small
bends and recheck the movement of the choke
plate. Repeat this step until full movement is
achieved.
4. Reassemble by following step 1 in reverse order.
5. Test run the engine before returning to service.
