Safety & Operating Instructions

To Adjust the Throttle Cable

WARNING: Always disconnect the spark plug wire before servicing your machine.

CAUTION: Adjusting the throttle is a delicate procedure. There is only a few rpm difference between

the engine's idle speed and engagement of the centrifugal clutch.

The Throttle Cable is set at the factory and generally no service is required. However, when

replacing the throttle cable it is important to follow these steps:

Tools Needed:

• 5/16 wrench or socket.

1. Loosen the screw on the throttle cable clamp (Bowden clamp) with the wrench or socket so the

throttle cable can slide below it. It is not necessary to remove the clamp.

2. Remove the throttle from the handlebar.

3. Place the new throttle on the handlebar and fasten.

4. Rout the cable the same as the old cable, being careful not to bend or kink the cable.

5. Place the Z bend end of the throttle cable into the small hole on the throttle plate on the engine.

The throttle plate is a black tab that protrudes from the engine below the plastic air filter cover

and above the white choke lever. It has two holes, and the cable goes into the smaller hole.

Place the throttle cable sheath under the cable clamp.

6. Make sure that the throttle plate is all the way back to the stop. It will normally retract to this

position.

7. Make sure the return spring is attached from the zinc plated bracket to the black throttle plate. It

attaches to the larger of the two holes. Note: On some models the throttle spring is attached to

the Z bend at the end of the cable. If your Powerwagon is like this then it is necessary to

disconnect the spring from the cable. Otherwise, it is not necessary to disconnect the spring.

CAUTION: Failure to place the throttle return spring on the machine could cause the Powerwagon to

creep or lurch forward when placed in gear.

8. Tighten the cable clamp screw (Bowden clamp). The throttle cable should have very little or

no tension between the cable clamp and the throttle plate. If the cable is clamped with too

much tension between these points the engine will not return to idle properly.

9. Start the engine and check the operation of the machine. The DR

should idle smoothly, but

should not move while in idle, and should not jump after being put into gear.
