The warm weather is finally here, and you’re ready to get your Craftsman riding lawn mower out of storage and tackle that overgrown lawn. But before you can start mowing, you need to make sure your mower is primed properly. This article will walk you through the steps of priming your Craftsman riding lawn mower, from identifying the priming bulb to understanding its importance. We’ll also cover some essential tips to ensure your mower starts smoothly and runs efficiently.
A Quick Primer on Priming
Priming your Craftsman riding lawn mower is an essential step before starting it. This process ensures that the fuel system is adequately filled with fuel, facilitating a smooth and efficient start. The priming bulb, often located near the carburetor, helps to draw fuel into the system, making it easier for the engine to ignite.
Understanding the Importance of Priming
Priming your Craftsman riding lawn mower is crucial, particularly after prolonged storage or when using fresh gasoline. Here’s why:
1. Fuel Evaporation
During storage, gasoline can evaporate, leading to an air pocket in the fuel lines. This air pocket prevents the fuel from reaching the carburetor, making it difficult to start the engine.
2. Fuel Line Problems
Over time, fuel lines can become dry and brittle. This can cause fuel leaks or blockages, hindering the flow of fuel to the engine.
3. Air in the Fuel System
Even if you haven’t stored your mower for long, air can still get into the fuel system. This can happen when you fill the tank or if there are leaks in the fuel lines.
By priming your mower, you force fuel into the system, displacing any air pockets and ensuring a consistent fuel supply.
How to Prime Your Craftsman Riding Lawn Mower: A Step-by-Step Guide
1. Locate the Priming Bulb
The priming bulb is typically located near the carburetor. It’s usually a small, round, rubber bulb with a clear or opaque cover.
Tips for Locating the Priming Bulb:
- Refer to your Craftsman riding lawn mower’s manual for specific instructions on finding the priming bulb.
- Look for a bulb that’s connected to a fuel line.
- If you can’t find the priming bulb, it may be integrated into the fuel tank cap or another part of the fuel system.
2. Prepare the Mower for Priming
Before you start priming your Craftsman riding lawn mower, ensure that the choke is off and the ignition key is turned to the “Off” position.
3. Prime the Fuel System
With the mower prepared, you can begin the priming process:
- Squeeze the Priming Bulb: Gently squeeze the priming bulb several times, until it feels firm and you see fuel flowing through the transparent portion of the bulb. This usually takes around 5-10 squeezes.
- Check for Leaks: After squeezing the bulb, check for any fuel leaks. If you see any leaks, stop and inspect the fuel lines and connections for damage.
- Wait a Few Seconds: After priming the system, allow a few seconds for the fuel to flow to the carburetor.
4. Start the Engine
Once you’ve primed the fuel system, you can now start the engine. Here’s how:
- Turn the Ignition Key to “On”: Make sure the choke is off.
- Start the Engine: Turn the ignition key to the “Start” position and allow the engine to crank. It should start easily after you prime the system.
Troubleshooting Common Problems
If your Craftsman riding lawn mower doesn’t start even after priming, there could be a few issues:
1. Old Gasoline
Old gasoline can gum up the carburetor and hinder starting. Consider draining the old gasoline and replacing it with fresh fuel.
2. Clogged Fuel Lines
Fuel lines can become clogged with debris or sediment over time. Inspect the fuel lines for blockages and clean them if necessary.
3. Spark Plug Issues
A fouled or damaged spark plug can prevent the engine from igniting. Check the spark plug condition and replace it if needed.
4. Air Filter Problems
A dirty air filter can restrict airflow to the engine, making it difficult to start. Clean or replace the air filter as needed.
5. Carburetor Issues
The carburetor may require cleaning or adjustments. Consult your owner’s manual or a qualified mechanic for assistance.

FAQ
1. Why Do I Need to Prime My Craftsman Riding Lawn Mower?
Priming your Craftsman riding lawn mower is crucial for ensuring a smooth start, especially after long periods of storage. When the engine is inactive, the fuel lines and carburetor can dry out, leading to air pockets that prevent fuel from reaching the combustion chamber. Priming manually introduces fuel into the carburetor, eliminating these air pockets and making it easier for the engine to ignite.
Essentially, priming acts as a quick “jumpstart” for your lawn mower’s engine, ensuring that fuel is readily available for ignition. This is particularly beneficial after periods of inactivity, such as during winter storage, as it prevents you from struggling with a reluctant engine.
2. How Often Should I Prime My Craftsman Riding Lawn Mower?
You generally only need to prime your Craftsman riding lawn mower when it hasn’t been used for a while. This typically means after winter storage or if it’s been sitting idle for several weeks. If you use your mower regularly, you shouldn’t need to prime it every time.
However, if you notice difficulty starting the engine after a short break, you can try priming it to see if it helps. It’s always a good idea to consult your Craftsman riding lawn mower’s manual for specific recommendations based on your model.
3. Where Is the Primer Bulb Located on My Craftsman Riding Lawn Mower?
The primer bulb is usually located on the carburetor of your Craftsman riding lawn mower. It’s typically a small, round bulb made of rubber or plastic. Look for it near the air filter or fuel lines.
If you can’t find it, consult your Craftsman riding lawn mower’s manual, which will provide a diagram showing the location of the primer bulb. If you’re still having trouble, reaching out to Craftsman customer support or a local lawn mower repair shop could be helpful.
4. How Many Times Should I Pump the Primer Bulb?
The number of pumps required to prime your Craftsman riding lawn mower can vary depending on the model and how long it has been sitting. A general rule of thumb is to pump the primer bulb 3-5 times.
If you’re unsure, check your Craftsman riding lawn mower’s manual for specific instructions. Remember, it’s better to err on the side of caution and pump the primer bulb a few extra times rather than not enough.
5. What Happens if I Pump the Primer Bulb Too Much?
Pumping the primer bulb too much can lead to flooding the carburetor. This can result in difficulty starting the engine and may even damage the spark plugs. If you think you’ve pumped the primer bulb too much, try starting the engine without pumping the bulb again.
If the engine doesn’t start, allow a few minutes for the excess fuel to evaporate before trying again. If the problem persists, consult your Craftsman riding lawn mower’s manual or a qualified mechanic.
6. Can I Prime My Craftsman Riding Lawn Mower With the Engine Running?
No, you should never prime your Craftsman riding lawn mower with the engine running. This could be extremely dangerous, as it could lead to an uncontrolled release of fuel and potentially cause a fire. Always make sure the engine is off and the ignition key is removed before priming the carburetor.
Always follow safety precautions when dealing with gasoline and engine components. If you’re unsure about any step, it’s always best to consult your Craftsman riding lawn mower’s manual or seek professional assistance.
7. How Do I Know If My Craftsman Riding Lawn Mower Needs a New Primer Bulb?
If your primer bulb is hard or cracked, it’s a sign that it’s worn out and needs to be replaced. A damaged primer bulb can affect the amount of fuel entering the carburetor, making it difficult to start the engine.
Check the primer bulb regularly for signs of damage. If you notice any issues, replace it immediately with a new one. You can find replacement primer bulbs at most hardware stores or online retailers.
