There are six different chains with different pitches that can be used on this saw. 1/4, 3/8 PMN, and 3/8 P use a 5/32" file; 0.325 uses a 3/16" file; 3/8 uses a 13/64" file; and 0.404 chain uses a 7/32 file. The pitch is ususally stamped on the side of the chain teeth.
Your chainsaw is running-lean, take off top cover. You should see the air filter. Under The plastic air filter housing is too nuts, 12mm socket is Wot you need next, you need to check these too nuts are tite, these nuts hold the carby to the Intake, all air that goes into the saw is mixed by the carby with fuel. Your saw is running lean. So if those bolts are tite you'll need to check the gasket between the carby and the block....... There are others possibilities but these too are your most likely.
It probably goes to the ground on the choke lever. Remove the air filter and look at the area where the shut off switch is located, you should see a small slot where the wire slides in and connects with a metal piece in the stop position.
The vent is not working properly or was installed incorrectly, so there is no negative air entering the tank to take up the space of the fuel leaving it for the combustion chamber. Perhaps your tank cap has a vent as well that isn't working.
If the lead is broken, depending on which saw it is, you can buy a replacement lead. Unscrew the wire from the ignition module and screw in the new one after you put the end and boot on it. If it doesn't unscrew then you will have to buy a new module 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'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.
