You can check and see if the filter is clogged. Then check the muffler.

You've got a carb jet/orifice plugged. It's likely a tiny piece of grass, or dirt, or even gas crud. It's also remotely possible that the gasket between the carb & engine has a tiny little leak.

Did you also clean the vents around the air filter cover and where the air filter sits in the engine. Use a little bit of gas and a toothbrush, and then wipe it clean with the rag.

When you removed the muffler cover did you pull out the spark arrestor screen and clean it with a toothbrush and rag? Also check for any debris inside the muffler and clean if necessary. Put the trimmer back together and try starting again.

You can also empty the gas tank and wrap a rag around a toothbrush and spray a little carburetor cleaner into the tank and clean it then disconnect the fuel line from the carburetor and pull out the old fuel filter and fuel line. Replace both of these. Fill the trimmer with freshly mixed gas at a 50:1 gas-oil mixture and make sure the primer bulb is filling with gasoline. Pump it seven times on setting one. Pull on the starter cord until it pops and dies. Move it to setting two and pump the primer bulb two times. Start it again and let it idle, without throttling it, for a few minutes. Set to the final position and start it again and adjust the carburetor by resetting the high and low carburetor screws. Turn them in clockwise all the way seated, and then back out a 1/4 to 1/5 turn on both screws. Fine tune these screws with the engine running and throttled.

If you still have a problem, remove, disassemble, and clean the carburetor if the trimmer still isn't starting. Soak all of the parts in a carburetor bath for at least 24 hours. Scrub them with a heavy wire brush and use a carburetor kit to replace any worn out parts. If you did all this and you still have a problem then I would sugges to contact a knowledgeable professional if you're in doubt about any of the recommended repairs.

Also check your exhaust holes on your muffler for any debris which will also cause the thing to bog down. On your muffler there should be a plate with 3 torx screws, remove them and the plate to expose the exhaust holes.

Those orifices are SO tiny that it doesn't take much to plug them.

The fact that it idles with the choke on indicates that your spark plug is fine, and that the engine itself is okay. The problem is that you're not getting ENOUGH gas to do more than idle. The primary jet/orifice is probably the culprit.
