My first Troy Bilt trimmer broke, but lucky I got the ext. warranty. Now my new one broke but it is not covered so I took it apart. I found that at the drive shaft it had sheared off the indent because it was made out of cast aluminum so the whole starting assembly was free spinning on the shaft insead of turning it. So now I need a new part and it will probably happen again. Poor engineering.

With 2 cycle the oil can leave deposits in the carb and cylinder causing problems. Sounds like the carb is gummed up.
You can undo the sprak plug, then reconnect the plug wire and leave the spark plug touching part of the engine (any metal) and pull the string. If you have spark you will see it. Doing this in the shade or dim area is easiest to see if it is sparking.
