  • If cleaning doesn’t solve the problem, consider replacing the carburetor altogether.

Fixing A Dead Battery

There’s nothing more frustrating than starting up your craftsman riding mower, only to find that it won’t start. One of the most common causes of this issue is a dead battery. Before you rush out to buy a new battery, there are a few simple steps you can take to troubleshoot and potentially fix the problem.

Jump-Starting The Mower

If your craftsman riding mower won’t start due to a dead battery, you can try jump-starting it using the following steps:

  • Ensure that the ignition switch is in the “off” position and set the parking brake.
  • Connect the positive (red) jumper cable to the positive terminal of the dead battery.
  • Connect the other end of the positive jumper cable to the positive terminal of a fully charged battery.
  • Connect the negative (black) jumper cable to the negative terminal of the fully charged battery.
  • Attach the other end of the negative jumper cable to a metal part of the mower frame, away from the battery and fuel system.
  • Start the mower and let it run for a few minutes to allow the dead battery to charge.

Charging The Battery

If jump-starting the mower doesn’t work or if you don’t have access to a fully charged battery, you can try charging the dead battery with a battery charger. Here’s how:

  • Remove the battery from the mower and place it in a safe, well-ventilated area.
  • Connect the charger’s positive cable to the positive terminal of the battery.
  • Connect the charger’s negative cable to the negative terminal of the battery.
  • Set the charger to the appropriate charging voltage and amperage for your battery.
  • Plug in the charger and let it charge the battery for the recommended time.
  • Once the battery is fully charged, disconnect the charger and reinstall the battery in the mower.

Replacing The Battery

If jump-starting and charging the battery don’t work, it might be time to replace the battery. Follow these steps to replace the dead battery:

  • Remove the battery from the mower.
  • Check the battery’s label and ensure the replacement battery has the same voltage and dimensions as the original battery.
  • Install the new battery in the mower, connecting the positive cable to the positive terminal and the negative cable to the negative terminal.
  • Double-check all connections to ensure they are secure.
  • Start the mower and test to see if it starts without issues.

Remember, a dead battery is a common problem that can prevent your craftsman riding mower from starting. Following these steps to jump-start, charge, or replace the battery, you can get your mower up and running again in no time.

Fixing A Faulty Starter Motor

Riding mowers are convenient for maintaining a beautiful lawn, but what happens when your craftsman riding mower won’t start? One common culprit could be a faulty starter motor. This section will explore how to fix this issue and get your mower up and running again.

Checking The Starter Solenoid

Before diving into the starter motor, it’s important to ensure that the starter solenoid functions correctly. Here are some key points to keep in mind:

  • Inspect the battery connections to make sure they are clean and tight.
  • Check for any corrosion or damage on the solenoid terminals.
  • Use a multimeter to test the continuity between the solenoid terminals.

Testing The Starter Motor

If the solenoid checks out, it’s time to move on to testing the starter motor. Here’s what you need to know:

  • Locate the starter motor, typically situated on the engine’s side.
  • Inspect the motor for any visible signs of damage or wear.
  • Connect the positive lead of a multimeter to the motor’s positive terminal and the negative lead to a good ground.
  • Turn the ignition key to the start position and observe the multimeter readings.

Replacing The Starter Motor

If the starter motor fails the tests, it’s likely time to replace it. Consider these steps:

  • Disconnect the battery to ensure safety during the replacement process.
  • Remove any necessary components to access the starter motor.
  • Disconnect the wiring harness and mounting bolts to detach the old motor.
  • Install the new starter motor in the reverse order, ensuring all connections are secure.

By following these steps, you can diagnose and fix a faulty starter motor, getting your craftsman riding mower back on track. Remember to always prioritize safety and consult the manufacturer’s instructions for specific guidance.

Fixing A Clogged Carburetor

Craftsman riding mowers are a popular choice for homeowners to maintain their lawns effectively. However, it can be frustrating when your trusty riding mower refuses to start. One common issue that may be preventing your craftsman riding mower from starting is a clogged carburetor.

The carburetor plays a crucial role in the proper functioning of the engine, and when it is clogged, it can cause the mower to fail to start. In this section, we will explore how to fix a clogged carburetor and get your craftsman riding mower up and running again.

Cleaning The Carburetor

Cleaning the carburetor is the first step to take when troubleshooting a clogged carburetor. A clogged carburetor can occur due to a buildup of debris or old fuel residue. Here are the key points to keep in mind when cleaning the carburetor:

  • Start by disconnecting the spark plug wire to ensure safety.
  • Remove the carburetor from the mower and disassemble it carefully.
  • Use a carburetor cleaner to spray and clean the different components of the carburetor thoroughly.
  • Pay special attention to the small openings and passages, ensuring they are free from any debris or clogs.
  • Reassemble the carburetor and reinstall it on the mower.

Adjusting The Carburetor Settings

If cleaning the carburetor doesn’t solve the issue, you may need to adjust the carburetor settings. Here’s what you need to know about adjusting the carburetor settings:

  • Locate the idle adjustment screw on the carburetor and adjust it to the recommended settings specified in the owner’s manual.
  • Similarly, locate the high-speed adjustment screw and adjust it according to the manufacturer’s guidelines.
  • It’s important to make small adjustments at a time and test the mower after each adjustment to ensure optimal performance.

Replacing The Carburetor

If cleaning and adjusting the carburetor settings do not resolve the starting issue, it may be necessary to replace the carburetor. Here’s what you should keep in mind when replacing the carburetor:

  • Identify the specific carburetor model for your craftsman riding mower and purchase a replacement carburetor.
  • Disconnect the fuel line and remove the old carburetor from the mower.
  • Install the new carburetor and connect the fuel line securely.
  • Ensure all connections are properly tightened.
