The warm weather has finally arrived, and with it comes the dreaded task of mowing the lawn. But before you can tackle those overgrown patches, you need to make sure your trusty Craftsman M110 lawn mower is ready to go. Getting a stubborn lawn mower to start can be frustrating, but with a few simple steps and a little troubleshooting, you’ll be back on track to a perfectly manicured lawn in no time. This comprehensive guide will cover everything you need to know, from basic starting procedures to identifying and fixing common issues that might be preventing your M110 from firing up.

A Quick Overview

Starting a Craftsman M110 lawn mower is a relatively straightforward process. It involves ensuring the mower has enough fuel, the engine is primed, and the choke is properly engaged. This guide will provide a step-by-step breakdown of the process, as well as address common problems you might encounter, such as a dead battery, clogged carburetor, or faulty spark plug.

Pre-Start Checklist: Making Sure Your M110 is Ready to Go

Before you even attempt to start your Craftsman M110, it’s important to go through a simple pre-start checklist. This ensures that your mower is in optimal condition and ready to run smoothly.

1. Fuel Check: Is Your M110 Hungry?

The first step is to ensure your mower has enough fuel.

  • Check the fuel level: Look at the fuel tank and ensure it has enough fuel.
  • Fresh fuel is best: Old gasoline can cause problems, so use fresh, high-quality gasoline.
  • Fuel stabilizer: If you won’t be using the mower for a while, adding fuel stabilizer can help prevent fuel degradation.

2. Oil Level: Keeping Your Engine Happy

The engine oil lubricates the moving parts, preventing wear and tear.

  • Check the dipstick: Remove the dipstick and wipe it clean. Insert it back in and remove it again. Check the oil level on the dipstick and ensure it’s within the “Full” range.
  • Top off if needed: If the oil level is low, add the appropriate type and amount of oil.

3. Blade Check: Sharp and Ready

A sharp blade ensures a clean cut and prevents damage to your lawn.

  • Inspect for damage: Check the blade for any signs of damage, such as nicks or bends.
  • Sharpen or replace: If the blade is dull or damaged, sharpen it or replace it with a new one.

Starting Your Craftsman M110: A Step-by-Step Guide

Now that you’ve completed the pre-start checklist, you can move on to starting your Craftsman M110:

  1. Position the Mower: Place your mower on a flat surface. It should be on solid ground, not a soft surface like grass.

  2. Engage the Choke: The choke restricts airflow to the engine, helping it start in cold conditions. Locate the choke lever and move it to the “choke” position.

  3. Prime the Engine: For a cold engine, priming can help ensure a smooth start. Locate the primer bulb and press it 3-5 times to push fuel into the carburetor.

  4. Turn the Key to “On”: Make sure the key is in the “On” position. Some Craftsman M110 mowers have a separate ignition switch. If yours does, ensure it is also in the “On” position.

  5. Pull the Starter Cord: Gently pull the starter cord until you feel resistance, then pull it firmly and quickly.

  6. Disengage the Choke: Once the engine starts, gradually move the choke lever to the “run” position. You may need to gradually disengage the choke over a few seconds.

  7. Let the Engine Warm Up: Let the engine run for a few minutes to ensure it reaches operating temperature.

Troubleshooting Common M110 Starting Problems

Even after following the steps above, your Craftsman M110 may still refuse to start. Don’t panic! Here are some common problems and their solutions:

1. Dead Battery (For Electric Start Models):

  • Check the battery: Look for a loose connection or corrosion on the battery terminals.
  • Jump start: If the battery is dead, you may be able to jump start it using jumper cables.
  • Replace the battery: If the battery is old or faulty, replace it with a new one.

2. Clogged Fuel Line or Carburetor:

  • Inspect the fuel line: Look for any kinks or blockages in the fuel line.
  • Clean the carburetor: A clogged carburetor is a common problem. You can clean the carburetor yourself or take it to a qualified repair shop.

3. Faulty Spark Plug:

  • Check the spark plug: Remove the spark plug and check for damage or wear.
  • Replace the spark plug: If the spark plug is faulty, replace it with a new one of the correct type.

4. No Spark:

  • Check the ignition system: If there’s no spark, there may be an issue with the ignition system, including the spark plug wire, ignition coil, or magneto.
  • Consult a mechanic: If you suspect an issue with the ignition system, consult a qualified mechanic.

Maintaining Your Craftsman M110: Ensuring Long Life

Regular maintenance is crucial for keeping your Craftsman M110 running smoothly and extending its lifespan.

1. Oil Changes:

  • Change the oil regularly: Consult your owner’s manual for the recommended oil change intervals.
  • Use the right oil: Use the type and grade of oil specified in the manual.

2. Air Filter Cleaning:

  • Clean the air filter: A dirty air filter can restrict airflow to the engine, leading to performance issues.
  • Replace the air filter: Replace the air filter if it’s damaged or excessively dirty.

3. Blade Sharpening:

  • Sharpen the blade regularly: Sharpen the blade every few uses or as needed.
  • Replace the blade: Replace the blade if it’s damaged or worn beyond repair.
