The part(s) or condition(s) listed below for the symptom Edger won't start are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
The spark plug ignites the fuel and air mixture in the engine's cylinder to power the engine. If the spark plug is defective, the engine may not start. To determine if the spark plug is defective, remove the spark plug and inspect it. If the porcelain insulator is cracked, an electrode has been burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. Alternatively, if the spark plug hasn’t been replaced in a few seasons, replace it.
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the edger for a long period of time. Over time, some of the ingredients in the fuel will 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.

Before you replace the ignition coil, make sure that the spark plug is in working condition. If you have confirmed that the spark plug is not defective, test the ignition coil using an ignition coil tester. If the ignition coil is defective, replace it.
