Compatibility
This kit is specifically engineered for use with Craftsman M110 140cc Lawn Mowers. Ensure your mower model matches this specification for proper fit and function.
Kit Contents
- Two (2) Air Filters (Dimensions: approximately 4.5 x 2.5 inches each)
- One (1) Spark Plug (Hex size: 0.5-inch)
Installation Instructions
Before beginning any maintenance, ensure the lawn mower engine is cool and the spark plug wire is disconnected to prevent accidental starting.
1. Air Filter Replacement
- Locate the air filter housing on your Craftsman M110 140cc lawn mower.
- Open or unclip the air filter housing cover.
- Carefully remove the old air filter. Note its orientation.
- Insert a new air filter from the kit into the housing, ensuring it is seated correctly.
- Close and secure the air filter housing cover.
2. Spark Plug Replacement
- Locate the spark plug on the engine. It will have a thick wire connected to it.
- Disconnect the spark plug wire by pulling firmly on the boot, not the wire itself.
- Using a spark plug wrench (not included), carefully unscrew the old spark plug counter-clockwise.
- Inspect the new spark plug for any damage. Ensure the gap is correct (refer to your mower's specific manual for gap specifications, if needed).
- Screw in the new spark plug by hand, clockwise, until it is finger-tight. This helps prevent cross-threading.
- Using the spark plug wrench, tighten the spark plug an additional 1/4 to 1/2 turn. Do not overtighten.
- Reconnect the spark plug wire firmly until it clicks into place.
Maintenance Tips
- Regular Inspection: Periodically check your air filter for dirt and debris. A clogged filter can reduce engine performance.
- Spark Plug Condition: Inspect the spark plug electrodes for wear or carbon buildup during routine maintenance. Replace if heavily fouled or worn.
- Storage: If storing the mower for an extended period, consider replacing the spark plug and air filter as part of your pre-storage maintenance.
- Refer to Mower Manual: Always consult your Craftsman M110 140cc lawn mower's official owner's manual for specific maintenance schedules and additional instructions.
Troubleshooting
If your mower experiences issues after replacing the components, consider the following:
- Engine Not Starting: Ensure the spark plug wire is securely connected. Verify the new spark plug is tightened correctly but not overtightened.
- Reduced Performance: Double-check that the air filter is installed correctly and the housing is sealed. An improperly seated filter can allow unfiltered air into the engine.
- Unusual Noises: Re-check all connections and ensure no tools or debris were left near the engine.
