Official Ace lawn edger parts

Top replacement parts for Ace lawn edgers

• Engine air filter. The edger's air filter removes contaminants from air before it reaches the engine, to help reduce engine wear and improve efficiency.
• Blade drive belt. The blade drive belt connects the engine pulley on the crankshaft to the blade pulley on the quill assembly to spin the edger blade.
• Engine flywheel key. The flywheel key is a small metal rectangle that keeps the crankshaft and flywheel aligned when you tighten the flywheel nut. To protect more expensive components from damage, the flywheel key is designed to shear if the edger blade hits an object hard enough to make the flywheel slip out of alignment with the crankshaft.
• Recoil starter assembly. The recoil starter assembly on top of the engine included a starter rope and a spring that retracts the rope.

Troubleshooting tips for your Ace lawn edger when its engine won't start

When you can't start your edger, make sure the tank has fuel and that the fuel is fresh; stale fuel can become watery and won't ignite well. Tune up the edger's engine to give it the best chance of starting. Check the spark plug and replace it if it's covered with oil or other deposits.

If you can't pull the starter rope, check for a hydraulic lock of the piston. Remove the spark plug and pull the starter rope to see if the recoil starter spins the engine. If it does, then oil likely filled the cylinder when you tipped the edger sideways or backwards. Reinstall the spark plug and try starting the engine. The engine may smoke as it burns off oil inside the cylinder then the engine may run smoothly.

Replace the engine safety switch or the ignition coil if the spark plug isn't getting current through the ignition system.

The engine won't start if you hit a rock or stump and shear off the flywheel key, so replace the flywheel key if it's broken.

Carburetor problems often prevent an edger engine from starting. Replace or rebuild the carburetor if it's clogged.
