It is a weed eater. And I just checked the spark arrestor screen and it is pretty clean. Trimmer is only a few years old so I didn't expect that to be too bad, but checked anyway.
I have a TB22 that refuses to start. I have replaced the spark plug, fuel line and carburetor. I follow the starting instructions but to no avail. It won't even act like it wants to run. It is 4 years old. What can I try?
