ENGINE RPM ADJUSTMENT
DANGER
• Do not operate gasoline vehicle in an enclosed area without proper ventilation. The engine produces
carbon monoxide, which is an odorless, deadly poison.
1. If the governor is adjusted, proceed to step 2; otherwise, adjust the governor. See Governor Cable Installation
and Adjustment on page 22-6.
2. Connect battery and spark plug wire(s). See Connecting the Battery – Gasoline Vehicles on page 1-4.
3. Place the Forward/Reverse handle in the NEUTRAL position, chock the wheels, and place the neutral lockout
cam in the MAINTENANCE position.
4. Connect a tachometer (P/N 1016112) to the spark plug lead.
5. With the tachometer connected, and the engine at normal operating temperature, check high speed RPM. With
the accelerator pedal pressed to the floor, the tachometer should read 2900 RPM (±30).
6. To reduce RPM, adjust the two lock nuts (12) to move the cable housing toward the rear of the vehicle until the
specified RPM is reached (Figure 22-6, Page 22-7) . To increase RPM, adjust the two lock nuts (12) to move the
cable housing forward until the specified RPM is reached.
7. Be sure both lock nuts are locked against the bracket and then check the RPM again. If the RPM needs to be
adjusted, repeat step 6.
8. If more adjustment is required than the cable housing will allow, make sure the spring on the other end of the
accelerator cable is properly positioned. Excessive belt and torque converter wear can also prevent proper RPM
adjustment. Check them for excessive wear. See Section 25 – Torque Converter (Gasoline Vehicle).
9. Check vehicle ground speed. See Governor Cable on page 22-6.
ENGINE BACKFIRE
If the pedal-start Kawasaki FE350 engine is “backfiring”, it is most likely a lean backfire originating in the exhaust
system due a lean fuel/air mixture. A lean backfire has the following characteristics:
• Occurs in the exhaust
• Generally occurs after pedal is reapplied
• Sounds range from a soft ‘pffft’ to a loud pop. Engines can exhibit a wide range of the sound.
To eliminate engine backfire, the carburetor pilot air screw and throttle idle screw must be adjusted.
Pilot Air Screw Adjustment
Adjust pilot air screw (3) (Figure 22-4, Page 22-4) out ( counterclockwise ) until it hits the stop (1/4 to 1/2 turn). No
tools are needed.
Throttle Idle Screw Adjustment
1. If throttle idle screw (2) (Figure 22-4, Page 22-4) is still at factory setting:
1.1. Back throttle idle screw out ( counterclockwise ) 1/4 to 3/8 turn.
1.2. Ensure the throttle idle screw is still in contact with throttle when pedal is up.
2. If throttle idle screw (2) is not at factory setting or if not sure:
2.1. Back throttle idle screw out ( counterclockwise ) until screw is not touching throttle.
2.2. Slowly adjust throttle idle screw in ( clockwise ) until screw just touches throttle. This can be accomplished
by gently holding throttle closed while adjusting screw. Go to next step when throttle just begins to move.
2.3. Adjust throttle idle screw in ( clockwise ) an addition 1/8 to 1/4 turn.
