Your lawn mower is a vital tool for keeping your yard looking its best. But what happens when it starts sputtering, coughing, and refusing to run smoothly? The culprit might be your carburetor. This vital engine component mixes fuel and air, and if it’s malfunctioning, your mower can’t get the fuel it needs to run properly. So, how much is a new carburetor going to set you back? In this guide, we’ll explore the factors that influence the cost of a lawn mower carburetor, break down the different types, and offer tips for finding the best deal.

The short answer? The price of a lawn mower carburetor can range from around $20 to over $100, depending on the make and model of your mower, the type of carburetor, and where you purchase it.

Factors Affecting the Cost of a Lawn Mower Carburetor

Several factors determine the price of a lawn mower carburetor. Understanding these factors can help you budget accordingly:

1. Make and Model of Your Lawn Mower

The make and model of your lawn mower play a significant role in determining the price of a replacement carburetor. Some brands are known for using higher-quality components, which can lead to higher prices for parts like carburetors. For example, a carburetor for a high-end, commercial-grade mower might cost more than one for a basic consumer model.

2. Type of Carburetor

Carburetors come in various designs, each with its own set of features and benefits. Common types include:

  • Diaphragm Carburetors: These are the most common type in modern lawn mowers. They are relatively inexpensive and offer good performance.
  • Float Carburetors: These carburetors are more complex and offer improved fuel efficiency but are generally more expensive.

The type of carburetor used in your mower will influence the price of a replacement.

3. Where You Purchase the Carburetor

The price of a carburetor can also vary depending on where you purchase it. Here’s a breakdown of common purchase options:

  • Local Lawn Mower Repair Shops: You can often find genuine parts at local repair shops, but prices may be higher due to markups.
  • Online Retailers: Online retailers like Amazon, eBay, and specialized parts websites offer a wide selection of carburetors at competitive prices.
  • Manufacturer Websites: You can sometimes find OEM (Original Equipment Manufacturer) parts directly from the manufacturer’s website, although prices may be higher.

4. Condition of the Carburetor

When buying a new carburetor, you’ll also encounter options for different condition levels:

  • New: A brand new carburetor is the most expensive option, offering optimal performance and the longest lifespan.
  • Reconditioned: Reconditioned carburetors are cleaned, inspected, and often rebuilt with new parts. These offer a good balance of price and quality.
  • Used: Used carburetors can be the most affordable option, but you’ll need to be extra cautious about their condition and potential for future problems.

How to Find the Best Deal on a Lawn Mower Carburetor

Here are some tips for finding the best deal on a new carburetor:

1. Research Your Mower’s Model Number

The first step is to identify your lawn mower’s model number. You can usually find this information on a sticker or plate located under the hood or on the frame.

2. Compare Prices From Multiple Sources

Once you have your model number, compare prices from different retailers. Look at both online and local options to get a sense of the market price.

3. Check for Manufacturer Rebates or Discounts

Some manufacturers offer rebates or discounts on parts. Check the manufacturer’s website or contact their customer service department to see if any offers are available.

4. Consider the Cost of Labor

If you’re not comfortable replacing the carburetor yourself, you’ll need to factor in the cost of labor from a qualified mechanic.

Alternatives to Replacing the Carburetor

Before you rush out to buy a new carburetor, consider some alternatives:

1. Clean the Existing Carburetor

Sometimes, a simple cleaning can restore your carburetor to proper working order. You can find cleaning kits specifically designed for lawn mower carburetors.

2. Repair the Existing Carburetor

If the carburetor is damaged but not beyond repair, you might be able to fix it yourself or have a mechanic do it. Repairing the carburetor can be less expensive than replacing it.

When to Replace a Lawn Mower Carburetor

You should consider replacing your carburetor if:

  • The engine won’t start: If the engine won’t start at all, a faulty carburetor could be the culprit.
  • The engine runs poorly: If the engine sputters, coughs, or stalls frequently, the carburetor may be malfunctioning.
  • The engine runs too rich or too lean: If the engine produces excessive smoke or runs erratically, you may have a carburetor issue.
  • The engine floods: A flooded engine often indicates a faulty carburetor.


Replacing a lawn mower carburetor can be a relatively affordable repair, but the cost can vary depending on a number of factors. By understanding the factors that influence the price, comparing options, and considering alternative solutions, you can make an informed decision that fits your budget and helps keep your lawn mower running smoothly.


Q1: What factors influence the price of a lawn mower carburetor?

The price of a lawn mower carburetor is influenced by a few key factors. Firstly, the brand and model of your lawnmower will determine the type of carburetor you need, and different manufacturers often charge different prices. Secondly, the size and complexity of the carburetor will play a role. Larger, more complex carburetors generally cost more than smaller, simpler ones. Lastly, the material the carburetor is made from can also affect its price.

For example, metal carburetors are usually more expensive than plastic ones, though they are also more durable.

Q2: Where can I find a replacement carburetor for my lawnmower?

There are several places you can find a replacement carburetor for your lawnmower. Your local hardware store or home improvement center is a good starting point. Online retailers such as Amazon and eBay also offer a wide selection of carburetors. If you have a specific brand or model of lawnmower, you may find it helpful to search for replacement parts directly on the manufacturer’s website.

Additionally, you can often find replacement parts at specialized lawnmower repair shops or dealerships. Be sure to check with your local stores and online retailers to see what kind of inventory they have and compare prices before making a purchase.

Q3: How do I know if I need a new carburetor?

Several signs may indicate your lawnmower’s carburetor needs replacing. If you notice your lawnmower is having trouble starting, running poorly, or stalling frequently, the carburetor may be clogged or malfunctioning. Additionally, if you’re experiencing excessive fuel consumption or seeing black smoke coming from the engine, it could be a sign of a faulty carburetor.

A malfunctioning carburetor can also lead to inconsistent engine performance, such as a lack of power or difficulty maintaining a consistent speed. If you observe any of these symptoms, it’s a good idea to check your carburetor for issues.

Q4: Can I clean my carburetor instead of replacing it?

Yes, you can often clean a lawnmower carburetor instead of replacing it. A dirty or clogged carburetor can cause many of the same problems as a faulty one. You can use a carburetor cleaning kit to remove dirt, debris, and fuel varnish from the carburetor.

If you’re comfortable working with small engine parts, you can try cleaning the carburetor yourself. However, if you’re unsure how to do it, it’s best to take your lawnmower to a repair shop.

Q5: Is it difficult to replace a lawnmower carburetor?

Replacing a lawnmower carburetor can range in difficulty depending on your experience and the specific model of your lawnmower. Some models have readily accessible carburetors, making the replacement relatively straightforward. Others may require more complex disassembly, which could be challenging for those unfamiliar with engine maintenance.

It’s essential to consult your lawnmower’s owner’s manual for specific instructions on replacing the carburetor. If you’re uncomfortable performing the replacement yourself, it’s best to seek professional help.

Q6: How can I ensure I get the right carburetor for my lawnmower?

When buying a new carburetor for your lawnmower, it’s crucial to ensure you get the right one. The easiest way to do this is to use the model number of your lawnmower. You can usually find the model number on a sticker attached to the lawnmower or in the owner’s manual.

If you don’t have the model number, you can try to match the carburetor’s physical characteristics to the old one. This includes the size, shape, and number of connections. However, it’s always safest to use the model number to ensure compatibility.

Q7: How long should a lawnmower carburetor last?

The lifespan of a lawnmower carburetor depends on several factors, including the quality of the carburetor, the type of fuel used, and how well the lawnmower is maintained. With proper care and maintenance, a lawnmower carburetor can last several years.

However, if you use low-quality fuel or neglect regular maintenance, the carburetor may need to be replaced sooner. It’s generally recommended to replace the carburetor every 5-7 years, even if it’s still working.
