How Much Is a New Carburetor for a Lawn Mower?

The whirring of a lawn mower is the soundtrack of summer, a symphony of power and precision that keeps your lawn looking its best. But what happens when that symphony falters? When your mower starts sputtering, refusing to cooperate, the culprit might be a malfunctioning carburetor. This vital component mixes fuel and air, ensuring a smooth combustion process. But when it goes bad, the cost of replacing it can vary widely. This article will delve into the factors that influence the price of a new carburetor, guiding you through the process of understanding the cost and choosing the right replacement for your specific lawn mower.

In short, the cost of a new carburetor for a lawn mower can range from $20 to $150 or more, depending on the mower’s brand, engine size, and the type of carburetor needed. But let’s break down these factors in more detail to provide a clearer picture.

Understanding the Factors Influencing Carburetor Cost

The price tag for a new lawn mower carburetor is influenced by several key factors that can significantly impact your budget:

1. Mower Brand and Model

Just like with any other part, the brand and model of your lawn mower play a significant role in determining the cost of a new carburetor. High-end mowers from brands like Honda, Briggs & Stratton, and Kohler often require more specialized parts, leading to higher prices. Older models may also have discontinued carburetors, driving up the cost due to the need to find compatible replacements.

2. Engine Size

The size of your lawn mower’s engine is directly linked to the complexity of its carburetor. Larger engines require more fuel and air, necessitating a more robust carburetor with larger components. As a result, carburetors for bigger engines are generally more expensive.

3. Type of Carburetor

The type of carburetor your mower uses also contributes to the price. Here’s a breakdown of common types:

a) Diaphragm Carburetors

These are the most prevalent type in lawn mowers, utilizing a diaphragm to regulate fuel flow. They are typically affordable, but the diaphragm itself can wear out, requiring replacement.

b) Float Carburetors

These carburetors use a float to maintain a constant fuel level. While generally more expensive than diaphragm carburetors, they offer a higher level of precision and are less susceptible to clogging.

c) Electric Carburetors

These are less common but offer the advantage of electronic fuel management. While they provide precise fuel delivery and improved efficiency, they often come with a steeper price tag.

4. Where You Buy Your Carburetor

The location where you buy your carburetor can significantly affect the price.

a) Local Mower Repair Shops

These shops usually carry a good selection of carburetors and can offer helpful advice on choosing the right one. However, they often charge a premium for parts and labor.

b) Online Retailers

Online retailers like Amazon, eBay, and specialty parts suppliers often offer competitive prices, but you’ll need to carefully verify compatibility before purchasing.

c) Dealerships

While dealerships offer genuine OEM (Original Equipment Manufacturer) parts, they generally come at a higher price.

Tips for Finding a New Carburetor at the Right Price

Now that you have a grasp on the factors affecting carburetor cost, here are some practical tips for finding the best deal:

  • Identify your mower’s brand, model, and engine size: This information will help you narrow down compatible carburetors and avoid unnecessary browsing.

  • Check online marketplaces and forums: Online communities like lawnmower forums and Facebook groups can provide valuable insights into finding compatible carburetors and potential discounts.

  • Consider a rebuild kit: If your carburetor’s only issue is worn-out parts, a rebuild kit might be a more affordable solution. It often contains a new diaphragm, float, needle, and other components, restoring your carburetor to working order.

  • Don’t neglect safety precautions: When handling fuel or working on your mower’s engine, always prioritize safety. Use appropriate protective gear, work in a well-ventilated area, and avoid open flames.

  • Explore DIY options: If you’re comfortable with basic engine maintenance, replacing a carburetor can be a DIY project. Numerous online tutorials and videos offer guidance on the process.


Replacing a lawn mower carburetor can be a worthwhile investment, restoring the power and efficiency of your mower. By understanding the factors influencing the cost and utilizing the tips provided, you can find the right carburetor at a price that suits your budget. Remember, a well-maintained lawn mower not only keeps your grass looking great but also contributes to a more environmentally friendly landscape. So, next time your mower starts sputtering, consider the investment of a new carburetor, and let the symphony of summer continue!


Q1: What factors influence the cost of a new lawnmower carburetor?

The price of a new carburetor for your lawnmower depends on several factors, including the brand and model of your mower, the engine size, and the complexity of the carburetor itself. For older mowers or those with unique engine configurations, finding a replacement carburetor can be more expensive. Additionally, the specific features of the carburetor, such as the number of jets or the presence of an electronic choke, can also impact its cost.

It’s always best to check with your local lawnmower repair shop or an online retailer for a precise price quote. Be sure to provide them with your mower’s make, model, and engine type for the most accurate information.

Q2: How much does a typical lawnmower carburetor cost?

The cost of a typical lawnmower carburetor can range from around $20 to $100. This price range covers the majority of common gasoline-powered mowers. Some cheaper models may have carburetors available for under $20, while high-end mowers or those with larger engines might require carburetors exceeding $100.

However, it’s crucial to remember that these are just general estimates. The exact price will always be specific to your mower model and the specific carburetor it uses.

Q3: Is it cheaper to replace the carburetor or the entire engine?

In most cases, replacing the carburetor is significantly cheaper than replacing the entire engine. Carburetors are generally affordable components, while a new engine can cost hundreds or even thousands of dollars.

However, if your engine is showing signs of significant wear or damage, replacing the carburetor might not be a long-term solution. It’s always advisable to consult with a qualified mechanic for a proper assessment before deciding on the best course of action.

Q4: Can I find a cheaper used carburetor?

While finding a used carburetor online or at a local lawnmower parts store might seem like an attractive option due to the lower cost, it comes with significant risks. Used carburetors might have hidden issues or be incompatible with your mower. Additionally, you might struggle finding the right one for your specific model.

It’s recommended to consider the potential savings against the potential risks involved before choosing a used carburetor.

Q5: Can I repair a damaged carburetor instead of replacing it?

In some instances, repairing a damaged carburetor might be a viable option. Simple issues like clogged jets or a faulty choke can often be addressed with a thorough cleaning and a few replacement parts. However, more complex repairs might require specialized tools and knowledge.

Before attempting a repair yourself, consult with a mechanic or a reputable repair guide. Improper repairs can lead to further damage and ultimately cost you more in the long run.

Q6: How do I know if my lawnmower carburetor needs replacement?

There are a few telltale signs that your lawnmower carburetor might be failing. These include difficulty starting the engine, inconsistent engine performance, poor fuel economy, excessive smoke, or a persistent smell of gasoline.

If you notice any of these symptoms, it’s best to have your carburetor inspected by a professional to determine the root cause of the issue.

Q7: What maintenance steps can I take to extend the life of my lawnmower carburetor?

Regular maintenance can significantly prolong the lifespan of your lawnmower carburetor. This includes:

  • Regularly cleaning the carburetor: This helps prevent clogging and ensures optimal fuel flow.
  • Using high-quality fuel: Avoid using old or contaminated fuel, as it can lead to carburetor issues.
  • Storing the mower properly: When not in use, store your mower with a full tank of gas and run it for a few minutes to help prevent carburetor issues.

Following these tips can help you avoid costly carburetor replacements and keep your mower running smoothly for years to come.
