4. Setup and Installation
Follow these steps carefully to replace the recoil pull starter on your Craftsman CMXGMAM2703840 lawn mower.
- Prepare the Mower:
- Ensure the lawn mower engine is off and has cooled down.
- Disconnect the spark plug wire from the spark plug to prevent accidental starting.
- Position the mower on a flat, stable surface.
- Locate the Old Starter: The recoil pull starter is typically located on the top or side of the engine, often covered by a shroud.
- Remove the Old Starter:
- Identify and remove the bolts or screws securing the old recoil starter assembly to the engine. Keep track of these fasteners.
- Carefully lift and remove the old starter assembly. If the rope is still attached to the engine, you may need to cut it or unthread it.
- Install the New Starter:
- Align the new RATION Recoil Pull Starter with the mounting holes on the engine.
- Insert the previously removed bolts or screws and hand-tighten them.
- Once all fasteners are in place, tighten them securely with the appropriate tool. Do not overtighten.
- Final Checks:
- Ensure the new starter is firmly mounted and does not wobble.
- Gently pull the starter rope a few times to ensure it extends and retracts smoothly without binding.
- Reconnect the spark plug wire to the spark plug.

5. Operating Instructions
Once the new recoil pull starter is installed, operate your lawn mower as per its original manufacturer's instructions. The pull starter functions identically to the original part.
- Ensure the mower's fuel tank is filled and the oil level is correct.
- Set the throttle to the "Start" or "Choke" position as required by your mower model.
- Grasp the starter handle firmly.
- Pull the rope with a smooth, steady motion until the engine starts. Do not yank or release the rope abruptly.
- Allow the rope to retract slowly back into the starter housing.
6. Maintenance
The RATION Recoil Pull Starter is designed for durability and requires minimal maintenance. However, periodic inspection can extend its lifespan.
- Keep Clean: Periodically clean any grass clippings, dirt, or debris from around the starter housing to prevent interference with the recoil mechanism.
- Inspect Rope: Check the starter rope for fraying or wear. If significant wear is observed, consider replacing the rope or the entire starter assembly if the rope is integrated.
- Check Mounting: Ensure the starter remains securely mounted to the engine. Tighten any loose fasteners.
7. Troubleshooting
If you encounter issues with your recoil pull starter, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Rope does not retract fully. | Spring issue, debris in housing, or rope binding. | Inspect for debris. If the spring is faulty, the starter may need replacement. |
| Starter rope pulls out but engine does not turn over. | Pawls not engaging flywheel, or engine issue. | Check if the pawls are extending. If not, the starter may be faulty. If pawls extend, consult your mower's engine manual for engine-related troubleshooting. |
| Starter feels stiff or hard to pull. | Engine compression, or internal starter friction. | Ensure spark plug is connected. If the engine is seized, consult a professional. If the starter itself is stiff, it may need replacement. |
