Quick Answer: The primer bulb on a Craftsman lawn mower is typically located near the carburetor, on the top or side of the engine. It’s a small, rubber bulb that you squeeze to prime the engine with fuel before starting.
Understanding the Primer Bulb
Before we dive into finding the primer bulb, let’s take a moment to understand its role. The primer bulb serves a crucial function in starting your Craftsman lawn mower. It helps to introduce fuel into the carburetor, creating a rich mixture that allows the engine to fire up more easily, particularly in cold weather or after extended periods of non-use.
Here’s how it works:
- Squeeze the primer bulb: This action draws fuel from the gas tank into the carburetor.
- Fuel fills the carburetor: The enriched fuel mixture helps the engine ignite and run smoothly.
- Engine starts: Once the engine starts, the primer bulb can be released, and the fuel delivery system takes over.
Common Locations for the Primer Bulb
Now, let’s get down to business and find that primer bulb! The exact location of the primer bulb can vary depending on the model of your Craftsman lawn mower. However, there are some common areas to look:
1. Near the Carburetor
The most likely location for the primer bulb is near the carburetor. The carburetor is the part of the engine responsible for mixing fuel and air. It’s typically located on top or near the side of the engine.
Where to look:
- Top of the carburetor: Check the top of the carburetor for a small, rubber bulb. It might be attached to a hose or directly to the carburetor.
- Side of the carburetor: Look around the sides of the carburetor for a primer bulb. It might be located in a small recess or on a side panel.
2. On the Engine Deck
Another common spot for the primer bulb is on the engine deck, which is the metal plate that covers the engine. It’s often located near the carburetor but might be placed on the opposite side of the engine deck.
Where to look:
- Along the edge of the engine deck: Inspect the edges of the engine deck, especially near the carburetor.
- Near the engine controls: The primer bulb may be located near the engine controls, such as the choke lever or the throttle control.
3. Under the Engine Cover
Some Craftsman lawn mowers have an engine cover that can be removed. The primer bulb might be located under this cover.
Where to look:
- Under the engine cover: Once you remove the engine cover, look for a primer bulb near the carburetor or engine controls.
4. In the Owner’s Manual
If you’re still struggling to find the primer bulb, don’t panic! The easiest and most reliable way to find it is by consulting your Craftsman lawn mower owner’s manual. The manual will provide detailed diagrams and instructions for locating and using the primer bulb.
5. Contact Customer Support
If you can’t find the owner’s manual or if you still can’t locate the primer bulb, contacting Craftsman customer support is your best option. They can assist you with identifying the location of the primer bulb specific to your model.
Tips for Identifying the Primer Bulb
Here are some tips to make the search for your primer bulb easier:
- Look for a small, rubber bulb: The primer bulb is typically a small, round, rubber bulb.
- Feel for a hose or pipe: The primer bulb might be connected to a small hose or pipe that leads to the carburetor.
- Look for markings: Some primer bulbs may have markings or labels, such as “Primer” or “Fuel Pump.”
When to Use the Primer Bulb
While the primer bulb is essential for starting a cold engine, it’s not necessary to use it every time. Here’s a general guideline for when to use the primer bulb:
- Cold engine: If your Craftsman lawn mower has been sitting for a while (more than a few days), you’ll likely need to use the primer bulb.
- Cold weather: In colder temperatures, the fuel may thicken, making it harder for the engine to ignite. Using the primer bulb will help to ensure a smooth start.
- After fuel changes: If you’ve recently changed the fuel in your lawn mower, priming the engine can be helpful.
Using the Primer Bulb
Once you’ve found the primer bulb, using it is simple:
- Squeeze the primer bulb: Press the primer bulb firmly several times (usually 3-5 times). This will draw fuel into the carburetor.
- Start the engine: Try to start the engine as you normally would. If it doesn’t start right away, squeeze the primer bulb a few more times and try again.
- Release the primer bulb: Once the engine starts and runs smoothly, you can release the primer bulb.
Conclusion
Finding the primer bulb on your Craftsman lawn mower doesn’t have to be a daunting task. By following the tips and guidelines in this article, you’ll be able to locate it quickly and efficiently.

Frequently Asked Questions
Where is the primer bulb on a Craftsman lawn mower?
The primer bulb on a Craftsman lawn mower is typically located on the carburetor, which is a small, round, black or red bulb. It’s usually situated near the air filter and fuel line, often on the side or top of the carburetor. To find it, look for a small, round bulb that can be squeezed.
If you’re still having trouble finding it, consult your Craftsman lawn mower’s user manual or search online for a diagram of your specific model. The user manual will provide detailed instructions and illustrations to help you locate the primer bulb and other important components.
Why do I need to use a primer bulb?
The primer bulb is an essential part of starting a cold engine on your Craftsman lawn mower. It helps to prime the carburetor with fuel, which makes it easier for the engine to start. When you squeeze the primer bulb, you’re forcing fuel into the carburetor, where it mixes with air and is then sent to the combustion chamber.
Without a primer bulb, starting a cold engine can be difficult, as the fuel may not reach the combustion chamber easily. By using the primer bulb, you’re essentially giving the engine a “jump start” and making it easier to fire up.
How do I use the primer bulb?
Using the primer bulb is a simple process. First, make sure the fuel tank is full and the choke is engaged. Next, squeeze the primer bulb several times until it feels firm. This will fill the carburetor with fuel. Finally, release the choke and pull the starter cord to start the engine.
It’s important to note that the number of squeezes required may vary depending on your specific model. Consult your Craftsman lawn mower’s user manual for specific instructions on how many times to prime the bulb.
How often should I use the primer bulb?
You should use the primer bulb every time you start your Craftsman lawn mower, especially if it’s been sitting for a while. This is because fuel can evaporate from the carburetor over time, making it difficult to start the engine. By priming the carburetor, you’re ensuring that there’s enough fuel for the engine to fire up.
You may not need to use the primer bulb if the engine is warm. However, it’s always a good idea to check the user manual for specific instructions on when to prime the carburetor.
What if I can’t find the primer bulb?
If you can’t find the primer bulb on your Craftsman lawn mower, it’s possible that your model doesn’t have one. Some newer lawn mowers have automatic priming systems that eliminate the need for a manual primer bulb.
If you suspect your model doesn’t have a primer bulb, consult the user manual or search online for information specific to your model. You can also contact Craftsman customer service for assistance.
What should I do if the primer bulb is cracked or leaking?
If your primer bulb is cracked or leaking, you should replace it as soon as possible. A cracked or leaking primer bulb can cause fuel to leak, which can be a fire hazard. It can also affect the performance of your engine, as it may not be able to draw in enough fuel to start.
To replace the primer bulb, you can purchase a new one from a local hardware store or online retailer. Be sure to choose a bulb that’s compatible with your specific model.
What are some common problems with primer bulbs?
Primer bulbs can sometimes become cracked or leak due to age or wear and tear. They can also get clogged with debris, which can prevent fuel from flowing through the carburetor.
If you’re having trouble starting your engine or you notice any fuel leaks, check the primer bulb for any signs of damage or clogging. If you suspect the primer bulb is the problem, replace it with a new one.
