Setup and Installation
This recoil starter is designed for a direct drop-in replacement. No modifications or special tools are typically required beyond standard hand tools.
- Prepare the Mower: Ensure the lawn mower engine is off and cool. Disconnect the spark plug wire to prevent accidental starting.
- Locate and Remove Old Starter: Identify the existing recoil starter assembly on your Craftsman M220 CMXGMAM211201 lawn mower. Carefully unbolt and remove the worn or damaged unit. Keep all original mounting hardware (bolts, washers) as they will be reused.
- Inspect Mounting Area: Clean any debris or grass clippings from the mounting area on the engine.
- Install New Starter: Position the RHYTHM TESTAMENT Pull Recoil Starter assembly onto the engine, aligning its mounting points with the factory hole pattern. The design is specific to the 21-inch deck layout of your mower.
- Secure the Starter: Reuse your original hardware to bolt the new starter assembly firmly into place. Ensure all bolts are tightened securely, but do not overtighten.
- Reconnect Spark Plug: Once the new starter is securely installed, reconnect the spark plug wire.



Operating the Pull Recoil Starter
After successful installation, operate the starter as follows:
- Ensure the mower's fuel tank is filled and the engine oil level is correct.
- Set the mower's throttle to the 'Start' position (if applicable) and engage the primer bulb a few times as recommended by your mower's manual.
- Grasp the T-handle firmly. Pull the rope slowly until you feel resistance, then give a quick, strong pull. Allow the rope to rewind smoothly.
- Repeat pulling until the engine starts. The balanced rotor and grippy T-handle are designed for confident engagement and quick starts.
Maintenance
To ensure optimal performance and extend the life of your recoil starter:
- Keep Clean: Regularly inspect the starter for grass clippings, dirt, or other debris. The vented guard helps clear clippings, but occasional cleaning can prevent buildup.
- Inspect Rope: Periodically check the starter rope for fraying or damage. Replace if necessary to prevent breakage.
- Smooth Rewind: Ensure the rope rewinds smoothly and completely after each pull. Consistent tension and rewind performance are crucial for reliable starts.
- Storage: If storing the mower for an extended period, ensure the starter mechanism is clean and dry.
Troubleshooting
If you encounter issues with your recoil starter, consider the following:
- Starter Rope Does Not Engage: Check if the internal pawls are stuck or if there's debris preventing engagement. Ensure the starter is properly seated and bolted.
- Rope Does Not Rewind: This could indicate a broken or tangled spring inside the assembly. If the spring is damaged, the entire assembly may need replacement.
- Hard to Pull: Ensure the engine itself is not seized or experiencing other issues. If the engine turns freely, check for internal friction within the starter assembly.
- Engine Not Starting: While the recoil starter provides the pull, ensure other mower components (fuel, spark plug, carburetor) are functioning correctly as per your mower's manual.
