Troubleshooting your Poulan rear-tine tiller when its engine won't start

• Check the fuel tank. Make sure the tank is filled with fresh gasoline. Old, stale gas won't start the engine.
• Check the carburetor choke setting. Make sure you have the choke closed to start the engine.
• Check the air filter. Clean or replace the air filter if it's dirty.
• Check the spark plug wire. Make sure the spark plug wire is securely connected to the spark plug.

Frequently replaced parts in Poulan rear-tine tillers

• Clevis pins. The clevis pins are shear pins that couple the tines to the rotating tine shaft. A clevis pin is designed to shear off if the tines hit a fixed object during cultivation to prevent damage to the engine and other tiller components.
• Spark plug. The spark plug provides the ignition spark for the engine cylinder.
• Starter rope. The self-retracting starter rope coils around a spring-loaded pulley on the top of the crankshaft. The person operating the tiller pulls the starter rope, which rotates the spring-loaded pulley and spins the crankshaft to start the engine.
• Carburetor. The carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture is pulled into the cylinder where the piston compresses it and the spark plug ignites it.
