How do I connect throttle cable to throttle trigger?

I'm sorry, but I can't provide a visual diagram as I can't display images or diagrams. However, I can give you a step-by-step guide on how to replace the throttle cable on a Stihl FS 55 weed eater.
Before you begin, make sure you have the necessary replacement parts and tools.
Materials and Tools:

• Replacement throttle cable
• Screwdriver
• Pliers
• Allen wrench
• Socket set

Procedure:

1. Safety First:
   • Ensure the weed eater is turned off, and the spark plug is disconnected to prevent accidental starts.
2. Remove the Air Filter Cover:
   • Locate the air filter cover on the weed eater's engine and remove it. Typically, this involves loosening screws or clips.
3. Access the Throttle Cable:
   • With the air filter cover removed, you should be able to see the carburetor and the throttle cable attached to it.
4. Disconnect the Throttle Cable:
   • Carefully disconnect the throttle cable from the carburetor. This might involve loosening a screw or bolt holding it in place. Note how it is routed and attached.
5. Remove the Handle Housing:
   • Locate the throttle trigger on the handle housing and remove it. This may involve unscrewing parts of the housing or loosening screws to access the cable.
6. Replace the Throttle Cable:
   • Feed the new throttle cable through the handle housing and reattach it to the throttle trigger. Make sure it's properly connected.
7. Reconnect at the Carburetor:
   • Reattach the other end of the throttle cable to the carburetor in the same manner it was originally connected.
8. Adjust the Cable Tension:
   • Adjust the cable tension to ensure it operates smoothly. There should be some slack when the trigger is released but no excessive play.
9. Reassemble the Weed Eater:
   • Reattach the air filter cover, making sure it's secure.
10. Connect the Spark Plug:
    • Reconnect the spark plug and ensure it's properly seated.
11. Test the Throttle:
    • With all the components reassembled, test the throttle to ensure it's working correctly.
12. Start the Weed Eater:
    • Reconnect the spark plug and start the weed eater. Verify that the throttle is responsive and functions as expected.

This is a general guideline for replacing the throttle cable on a Stihl FS 55 weed eater. Keep in mind that specific models may have variations in their design and components, so refer to the user manual or consult with a professional if you encounter any difficulties during the replacement process.

The throttle wire (From the trigger) seems to
be even cruder than a bicycle brake cable.

McCulloch Cable (bicycle type)

By looking at the pictures on eBay you
can see how simple the interfaces...
(triggers and wires are listed (fairly cheap here (USA)...

WIRE Type:
It appears the sheath is merely CRIMPED to
the trigger plate and the wire is only passes
through the TRIGGER HOLE (top wire only
(the bottom is not connected... as shown))

Happy hunting.. Hope this helps.

Check the throttle cable connection at the carburetor throttle linkage, it (cable) may be broken or the carburetor linkage is broke.

look at the cable did one of the ends break off?

A trimmer throttle cable can cost anywhere from $10-$25.

The wire linkage has a short Z bend in one end this hooks into the throttle lever from the outside, the other end has a long loop this goes into the trigger arm from the outside, you will need to twist the top of the trigger arm slightly to allow the linkage to go into the hole in the trigger arm.

It is quite difficult to explain exactly how it fits, the cable always looks too long and has to curl around on itself back to the trigger, the picture shows quite well how it goes, the end of the cable with a dog leg in it goes to the carb, as far as i remember it goes to the upper hole in the carb spindle, just push it into the hole and turn through 90%, the other end fits into the throttle trigger.

You should see some small wear marks inside the handle where the spring is supposed to rest. Also, check the throttle cable where it exits the plastic engine housing and goes to the throttle plate on the carburetor. Make sure it is connected correctly and not binding on anything on the way to the carburetor. There really aren't any diagrams or pictures available on the net of the insides of a Ryobi weed-trimmer's throttle trigger and spring.
When you squeeze the trigger the steel cable should move, the cable housing should NOT. If you look closely, you will maybe see how it works and all goes together. It is not that complicated.

On the carburetor hold the throttle lever to where it would be at full throttle. Then you can put the cable back in the catch for the cable that is on the throttle lever and let go of the throttle lever. The throttle cable should work with the throttle trigger now. The throttle cable only fits one way. The larger hole on the throttle cable catch should go to the ball at the end of the cable.
I hope this helps.
If you feel you cannot do this, then I would take it into your closest Stihl dealer and ask them if they would help you. I do this small repair for free at my shop. Have a good day.

Sorry there are no diagrams of how it fits, there is a parts list that shows the cable, as far as i remember the end of the inner cable has a dog leg in it, that hooks into the trigger, and the outer cable is secured in the right hand handle half, once the other half is assembled it stops it from popping out, the other end also has a dog leg this hooks into the throttle spindle, and the outer is secured in the air filter houseing.
