Craftsman Craftsman M110 140cc 21" Push Gas Lawn Mower MECH-PULL-CORD Error Fix: Pull Cord Breaks, Sticks, or Will Not Retract

Error code MECH-PULL-CORD on the Craftsman Craftsman M110 140cc 21" Push Gas Lawn Mower means: Pull Cord Breaks, Sticks, or Will Not Retract. The recoil starter pull cord breaks during a pull, gets stuck and will not pull out, or pulls out but does not retract/rewind into the housing. Causes: (1) Rope break — the cord is a nylon rope that wears and frays over time, especially at the handle mounting and where it wraps around the starter pulley. When it breaks, the mower cannot be started until the rope is replaced. Replacement recoil starter rope costs $3-$8, and the repair takes 15-30 minutes. Remove the starter housing, wind the new rope around the recoil pulley, thread through the housing, and attach the handle. (2) Rope will not retract — the recoil spring inside the starter housing is broken, unwound, or disconnected. The spring provides the force to rewind the rope. Spring replacement requires removing the starter assembly and carefully installing a new spring into the housing (the spring is under tension — wear gloves). Some people prefer replacing the entire starter assembly ($15-$35) rather than just the spring. (3) Rope stuck/hard to pull — the engine may be hydrolocked (oil or fuel in the combustion chamber), the blade is jammed against debris, or the engine has seized. Remove the spark plug and try pulling — if it pulls freely, fluid in the cylinder was the issue.
