MTD Hedge trimmer won't start
01 - MTD Hedge Trimmer Spark Plug
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. To determine if the spark plug is defective, use a spark plug tester. You should see a strong spark between the tester’s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced.

02 - MTD Hedge Trimmer Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the hedge trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

04 - MTD Hedge Trimmer Rewind Spring
The rewind spring might be broken. When the starter rope is pulled and released, the rewind spring recoils the starter rope onto a pulley. If the rewind spring is broken, the rope won’t be able to recoil onto the chainsaw pulley. As a result, the engine won’t start. If the rewind spring is broken, replace it. Many rewind springs can be replaced individually, but it may be easier to replace the whole recoil starter assembly.

If the hedge trimmer won't start the recoil starter assembly might not be engaging with the crankshaft and turning over the engine. Remove the starter assembly to see if it is functioning properly.
