Replace throttle cable - XLH Sportster 883 Hugger Harley Davidson Motorcycles

To replace the throttle on a Stihl FS38 weed eater, you'll need to follow these steps:

1. Disconnect the spark plug wire to prevent accidental starting.
2. Locate the throttle cable where it connects to the carburetor and carburetor housing.
3. Use pliers to loosen the lock nut on the carburetor side of the throttle cable and slide the cable out of the carburetor and carburetor housing.
4. Replace the throttle cable with the new one, feeding it through the carburetor and carburetor housing and tightening the lock nut on the carburetor side with pliers.
5. Check the operation of the throttle by starting the engine and confirming that the throttle cable moves freely and the engine speed changes accordingly when the throttle is manipulated.
6. Reconnect the spark plug wire.

It's recommended to consult your FS38's user manual for specific instructions as the process may vary slightly based on the model.

Simple solution: One of the two throttle cables has broken. Replace both throttle cables, and your problem will be solved. (Throttle cables on the Roadking are neither particularly expensive nor difficult to replace & adjust.)

throttle cable ??? should actually have a throttle rod that goes to a very short piece of cable. and this cable only goes from the carb to the throttle rod. the cable is actually easy to replace. it's only 3 inches long. the throttle rod or trigger requires removal of one side of the handle.

To replace the throttle cable, first loosen the adjustment on both cables getting as much slack as possible in both cables. Then remove the two screws that hold the right switch housing together. Carefully seperate the two halves of the switch housing. Work the cable out of their slots in the throttle sleeve. Do not lose the ferrels on the ends of the cables but do take them off. Work the broken cable out of the lower switch half.

To get the cable loose from the carburetor, you'll probably have to remove the fuel tank. With the fuel tank off, you can work the cable out of the cable stop and then out of the throttle plate linkage on the carburetor.

To install the new cable, first slide the new cable up through the hole in the lower switch housing. Then put the ferrels on the ends of both cables and work them back into their slots in the throttle sleeve. Carefully reassemble the switch housing halves back together being careful not to pinch any wires.

Then reconnect the cable at the carburetor throttle plate linkage and insert the new cable in the cable stop. Adjust the cable so that you have just a bit of freeplay in them and check to see if the throttle will snap closed on it's own when cranked to wide open throttle position and release. Make certain that the throttle works correctly. Put the fuel tank back on.

Good Luck

Remove the switch housing screws and spread it away. Loosen the adjuster locknuts on the throttle cables and adjust cables in, this will allow you to lift the cable off of the throttle grip. Be care full not to lose the barrels.( the small round caps on the end of the cable.) Assembly is the reverse. Make sure to check proper operation of the throttle before starting the bike.

Remove the seat, tank, and airbox. Follow throttle cable from the grip to the carbs seeing which way it is routed. Unscrew throttle housing and note which way the cable goes. Make sure when you replace the cable there is free play in the cable. Do not make the cable tight. Give slack in the throttle. Tighten. Twist throttle 10 times to make sure that there is no binding and a good snap! Chaz Moto DC

If you're talking about the old style throttle cable that is internal of the handlebar, it's pretty straight forward. Remove the throttle grip, the rollers and pin for the plunger. Pull the plunger out bringing the old throttle cable with it or at least out far enough to loosen the small set screws that lock the cable in. Now, run the new cable through the outer housing. put the end of new cable into the plunger and tighten the set screws. Replace plunger into the handlebar, replace pin and rollers, replace throttle grip. Now, set the throttle to full closed posititon. Move carb throttle lever to full closed position. With throttle cable through clamp tighten screw securing cable. Check for proper operation of throttle mechanism.
