Why Does the Carburetor Need to be Cleaned?

As anyone who has ever tried to start a hedge trimmer knows, a carburetor is an essential component of any small engine. The carburetor mixes air and gasoline vapor to create the combustible mixture that powers the engine. 

Over time, however, the carburetor can become clogged with debris, causing the engine to run less efficiently. In order to prevent this from happening, it is important to regularly clean the carburetor on your hedge trimmer.

There are a few reasons why the carburetor is particularly susceptible to debris build-up.

  • First of all, hedge trimmers are often used in dusty or sandy conditions, which can quickly clog up the carburetor.
  • In addition, hedge trimmers generate a lot of heat, which can cause gum and varnish to build up on the carburetor internals.
  • Finally, hedge trimmers are typically used for long periods of time, which gives debris plenty of time to accumulate. Consequently, regular cleaning is essential for keeping your hedge trimmer running smoothly.

How Often Should I Clean the Carburetor?

It’s generally a good idea to clean the carburetor once a year, at the beginning of the hedge trimming season. However, if you use your hedge trimmer regularly or if it’s been sitting idle for a long period of time, you may need to clean it more often. Signs that your carburetor needs to be cleaned include:

  • Difficulty starting the engine
  • Engine running Roughly
  • Loss of power while trimming
  • Black smoke coming from the exhaust 

If you notice any of these signs, it’s time to clean the carburetor.

Cleaning the Carburetor | A Step-by-step Guide

Once you’ve selected a cleaner, follow these steps to clean the carburetor: 

  1. Remove the air filter cover and set it aside. The air filter is usually located on top of the carburetor and is held in place by one or two screws.
  2. Remove the spark plug and set it aside. This will help prevent accidental starting while you’re working on the carburetor.
  3. Spray carburetor cleaner into all of the nooks and crannies of the carburetor, using care not to oversaturate any of the parts. Be sure to get into all of the small passageways and ports where dirt and debris can build up. Allow the cleaner to sit for 10-15 minutes so that it can break down any built-up grime.
  4. Use a small brush to scrub away any remaining dirt or debris from all surfaces of the carburetor, being careful not to damage any of the parts. If necessary, repeat steps 3-4 until all grime has been removed from the carburetor.
  5. Replace the spark plug and air filter cover and turn on the hedge trimmer to test whether or not it starts properly. If it doesn’t start immediately, give it a few more tries before assuming that something else is wrong. It may just take a little longer for gas vapors to clear out of the engine after being stored for an extended period of time.

You can use cleaners specifically designed for small engines. These cleaners will quickly and effectively remove any built-up grime in the carburetor without damaging any of the sensitive parts. 

You can find carburetor cleaners at most hardware stores or online retailers. Just be sure to follow the instructions on the cleaner carefully. Some cleaners need to be diluted with water before they can be used, while others can be used at full strength.  

Some Tips to Keep in Mind

Here are a few tips to keep in mind when cleaning the carburetor on your hedge trimmer to ensure the procedure goes smoothly:

  • Always wear safety glasses when working on your hedge trimmer.
  • Be sure to use a cleaner specifically designed for small engines. Household cleaners may not be safe to use and can damage delicate parts of the carburetor.
  • If the cleaner doesn’t seem to be working, try using a stiffer brush to remove the grime.
  • Do not use any compressed air when cleaning the carburetor, as this can cause damage to sensitive parts.
  • If your hedge trimmer still isn’t running properly after cleaning the carburetor, it may be time to take it in for service.
  • Always refer to the manufacturer’s instructions for any additional information about cleaning or maintaining your hedge trimmer.

Following these tips will help ensure that your hedge trimmer runs smoothly and efficiently all season long.


Cleaning the carburetor on your hedge trimmer may seem like a daunting task, but with the right cleaning supplies and some careful work, you can keep your hedge trimmer running smoothly for years to come. 

Just remember to be careful and follow the instructions on any carburetor cleaners you use, and always wear safety glasses while working. Be sure to do this at least once a year, or more often if necessary, to keep your hedge trimmer running like new for years to come!
