Craftsman S180 42cc Chainsaw MECH-PULL-CORD Error Fix: Starter Rope Breaks or Will Not Retract

Error code MECH-PULL-CORD on the Craftsman S180 42cc Chainsaw means: Starter Rope Breaks or Will Not Retract. The pull starter rope breaks during a pull, is stuck and will not pull out, or pulls out but does not retract back into the housing. Causes: (1) Rope worn and frayed — the nylon rope wears at the handle attachment and where it wraps around the starter pulley. It eventually breaks, leaving the operator unable to start the saw. Replacement rope and handle cost $5-$10 and the repair takes 20-30 minutes. (2) Recoil spring broken — the spring inside the starter housing provides the force to rewind the rope. When it breaks, the rope pulls out but does not retract. Replace the recoil spring (it is under tension — wear gloves and eye protection). (3) Rope jammed — the rope can tangle around the starter pulley or become wedged. Remove the starter housing and untangle/rewind the rope. (4) Engine hydrolocked — if the engine has drawn fuel into the cylinder (from storage on its side or a leaking carburetor), the piston cannot move and the rope feels locked. Remove the spark plug and pull the rope to clear the cylinder. (5) Engine seized — if the piston has seized from lack of oil or overheating, the rope will not move at all. This is typically a fatal engine failure.
