I would suggest finding an inline checker so you can visualize the spark without getting shocked for damaging the plug boot.
If your carb is working then when you take out your spark plug it should be covered with fuel. This could be a sign of no spark or it might be a sign of a dirty air filter causing an extreme rich condition. Try starting the saw with a clean plug and no air filter in place to rule this out. If it is dry you either have a fuel line issue or a blocked exhaust. Chain saws have spark arresting screens on them that can load up with unburnt fuel and oil *(from a bad carb or blocked air filter) be safe and good luck!
you have an air leak causing the unit to run to fast. The air leak is also over powering the flow of fuel causing it to die. Hopefully you have not tried running it repeatedly like this or you may have done severe internal damage due to running it to lean If you need further help, I’m available over the phone at https://www.6ya.com/expert/kelly_69a0cf1b13789df1
Suggest a cranckcase leak test to locate leak(s) other than rings. You need to seal the intake and exhaust ports and pressurize the crankcase via spark plug hole. No special tools other than an adapter from sparkplug hole to compressed air. The intake and exhaust ports can be sealed with pieces if old bicycle inner tube between carb and port and muffler and port. Then apply 5 to 10 psi to spark plug adapter. Spray case seams and shaft seals with WD40 or soapy water to locate slow leaks.Search "two cycle crankcase leak test" for videos.
I have been trying to find a new Trimming head for my Stihl FE 55 for about 4 years now, with no success. A British company say that their part no. 400471021932 fits my machine. I'm in South Africa but, and need to source one here.
It is a fuel / air problem. Do you have a primer bulb, did you replace it and put it in the right way around arrow to the carb? It is a known issue. There are lots of help online and there are some videos below..

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:
Safety First:
Ensure the weed eater is turned off, and the spark plug is disconnected to prevent accidental starts.
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.
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.
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.
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.
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.
Reconnect at the Carburetor:
Reattach the other end of the throttle cable to the carburetor in the same manner it was originally connected.
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.
Reassemble the Weed Eater:
Reattach the air filter cover, making sure it's secure.
Connect the Spark Plug:
Reconnect the spark plug and ensure it's properly seated.
Test the Throttle:
With all the components reassembled, test the throttle to ensure it's working correctly.
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.
I use an EGO 56 volt battery trimmer and did this the other day. I lost one end of the line inside after trimming along a brick wall. Under the spool they where two plastic tabs. I pressed them in and the top popped off. I removed the line and put the top back on and added new line as per instructions.

Easy way to figure it out without a diagram. Connect the filtered fuel line from the tank to either port of the carburetor. Leave other carb port open. Press purge bulb several times. If the filtered line is connected to the correct carb port, fuel will spurt out the open carb port. No fuel, switch filtered line to the other carb port and repeat purge to verify correct connection.
Warning, NEVER use the unfiltered fuel line for this procedure.
To replace the throttle on a Stihl FS38 weed eater, you'll need to follow these steps:
Disconnect the spark plug wire to prevent accidental starting.
Locate the throttle cable where it connects to the carburetor and carburetor housing.
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.
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.
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.
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.
