Important information about recoil starters

A broken recoil starter is generally not caused by the starter itself. It is designed to start an engine that must be able to turn freely during starting.

If the engine offers abnormal resistance, excessive force is placed on the starter rope and mechanism, which can cause the rope, pulley, pawls or other internal components to break.

Common causes of recoil starter failure

• Starter not compatible with the machine: the same machine model may be fitted with different engines and starters depending on its exact reference number and manufacturing date.
• Engine blocked or difficult to turn: seized piston, damaged bearing or another mechanical problem.
• Lack of oil or insufficient lubrication, which can cause the engine to seize.
• Excessive accumulation of oil or fuel in the cylinder, which can cause hydraulic lock (hydrolock).
• Decompression or valve problem on a 4-stroke engine, making the engine abnormally difficult to start.
• Repeated starting attempts when the engine is resisting or blocked.
• Pulling the starter rope too hard or all the way to its maximum extension, which can damage the mechanism.

Before replacing a broken recoil starter

If your recoil starter has broken quickly, it is essential to check that the engine turns freely before installing a new starter.

Replacing the starter without identifying the cause of abnormal engine resistance may result in the new part breaking immediately.

Check compatibility carefully

Before purchasing, always check the exact reference number and manufacturing date shown on your machine’s identification plate.

The same machine model may be fitted with different engines and recoil starters depending on its manufacturing period. Visual similarity between two starters does not guarantee compatibility.

The warranty cannot apply when the damage results from incompatibility with the machine, engine resistance or blockage, or abnormal mechanical stress on the recoil starter.
