Troubleshooting your Sears mower attachment when its engine won't start

• When you can't start your mower attachment's engine, 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 mower'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 your mower attachment engine uses a battery, charge or replace the battery if it won't power the starter to spin the engine. If you have to pull the starter rope to start the engine, replace the recoil starter if it doesn't spin the engine when you pull the rope. Replace the starter rope if it's broken.
• Replace the 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 a mower engine from starting. Replace or rebuild the carburetor if it's clogged.

Adjusting the blade clutch cable on your Sears mower attachment

• Remove the rear drive cover mounting screws then pull off the rear drive cover.
• Place the blade clutch lever in the disengaged position. The blade clutch cable should be under slight tension but should not pull the blade clutch lever more than 1/8-inch away from the switch body.
• To increase cable tension, loosen the inner nut on the clutch cable and tighten the outer nut on the clutch cable.
• To decrease cable tension, loosen the outer nut on the clutch cable and tighten the inner nut on the clutch cable.
• Reinstall the rear drive cover.
