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.

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.

H is for the high revs, high throttle

Not a great Stihl fan, however they usually have a single stop start, choke and half throttle lever, depress the throttle trigger and at the same time pull the lever fully uplet go of the throttle trigger which should now be lock up, this will engage the part throttle and choke, crank the machine until it fires once, then move the lever down one notch and crank again until it fires up.
