A Quick Overview of Starting a Craftsman M110
The Craftsman M110 is a reliable and popular gas-powered lawn mower known for its ease of use. However, like any engine, it requires proper maintenance and a few key steps to ensure a smooth start. Generally, starting your M110 involves preparing the mower, checking fuel and spark, and understanding the starting mechanism. We’ll delve deeper into these steps in the following sections.
Pre-Start Checklist: Setting the Stage for Success
Before attempting to start your M110, it’s essential to perform a quick pre-start checklist to ensure a safe and successful launch.
1. Safety First:
- Clear the Area: Ensure the area around your mower is clear of obstacles, children, and pets.
- Safety Glasses: Always wear safety glasses to protect your eyes from debris.
- Check for Loose Parts: Inspect the mower for any loose parts, especially the blade, before starting.
2. Fuel Up:
- Fresh Gas: Use fresh, high-quality gasoline with a minimum octane rating of 87.
- Fuel Levels: Check the fuel tank and make sure it’s not empty.
- Fuel Lines: Inspect the fuel lines for any cracks or leaks.
3. Prime the Engine (If Necessary):
- Primer Bulb: Some M110 models have a primer bulb on the carburetor. If yours does, squeeze the bulb several times to fill the carburetor with fuel before starting.
4. The Choke:
- Cold Start: For a cold engine, engage the choke (usually a lever on the handlebar). This enriches the fuel mixture for easier starting.
- Warm Engine: For a warm engine, disengage the choke.
Ignition Check: Is There a Spark?
The M110 engine needs a spark from the spark plug to ignite the fuel mixture. This step is crucial for successful starting.
1. Access the Spark Plug:
- Locate the Spark Plug: The spark plug is typically located on the top of the engine under a spark plug cap.
- Disconnect the Spark Plug Wire: Carefully detach the spark plug wire from the spark plug.
2. Check for Spark:
- Ground the Spark Plug: Hold the spark plug metal body against the engine block.
- Pull the Starter Cord: While holding the spark plug to the engine block, pull the starter cord several times. You should see a bright blue spark jumping across the spark plug gap.
3. Replace the Spark Plug Wire:
- If you see a healthy spark, reconnect the spark plug wire.
- If there’s no spark, you’ll need to troubleshoot the ignition system. This may involve replacing the spark plug, checking the spark plug wire, or examining the ignition coil.
Starting the M110 Engine
Now that you’ve confirmed a spark and performed the pre-start checklist, it’s time to attempt starting your M110.
1. Engage the Choke (If Needed):
- If your engine is cold, ensure the choke is engaged.
2. Pull the Starter Cord:
- Slow and Steady: Pull the starter cord slowly at first, building up to a steady pull.
- Multiple Attempts: It may take a few pulls to start the engine. Don’t give up!
3. Disengage the Choke:
- Once the engine starts, disengage the choke to allow for proper combustion.
Troubleshooting Starting Issues: When Your M110 Refuses to Co-operate
Sometimes, despite following these steps, your M110 might still be reluctant to start. Here are some common troubleshooting tips:
1. Fuel Issues:
- Empty Tank: Check your fuel tank and make sure it has enough gasoline.
- Clogged Fuel Lines: Inspect the fuel lines for any blockages or kinks.
- Dirty Fuel Filter: Replace the fuel filter if it’s dirty or clogged.
- Bad Gas: Old or stale gasoline can cause starting problems. If you haven’t used your mower in a while, drain the old fuel and replace it with fresh gasoline.
2. Spark Plug Issues:
- Old or Flawed Spark Plug: Replace the spark plug if it’s old, worn, or fouled with carbon deposits.
- Spark Plug Gap: Check the spark plug gap and adjust it if necessary. The proper gap for the M110 is usually 0.030 inches.
3. Starting Mechanism Problems:
- Clogged Air Filter: A dirty air filter can restrict airflow to the engine. Clean or replace the air filter.
- Battery Issues: If your M110 has an electric start, check the battery for a good charge.
- Damaged Starter Cord: Examine the starter cord for any wear or damage.
4. Engine Problems:
- Flooded Engine: If you’ve been trying to start the engine for a while, it may be flooded with too much fuel. To fix this, remove the spark plug and pull the starter cord several times to clear the excess fuel. Then, re-install the spark plug and try starting again.
- Engine Oil Issues: Check the oil level and make sure it’s full. Low oil levels can prevent the engine from starting.
