8 Possible Causes of Troy-Bilt Leaf Blower ROUGH Performance

When the engine of your leaf blower starts to perform poorly, check to see if the fuel, air, and spark settings are correct.

A Troy-Bilt leaf blower will start to misbehave if its fuel tank cover is broken, its fuel filter is blocked, its fuel line is kinked, its air filter is clogged, its spark plug is clogged, its spark arrestor is clogged, or the gasoline is old.

Always make sure the fan is turned off, the spark plug boot is removed, and everything has stopped moving before proceeding. Be cautious as you operate near the sizzling engine and muffler. Waiting for them to cool down is necessary to prevent harm.

8 Possible Causes of Troy-Bilt Leaf Blower ROUGH Performance

Before diagnosing, repairing, or using the equipment, be sure you’ve read and understood all of the safety precautions in the user handbook.

If you are unsure of how to proceed or if you lack the necessary expertise or physical ability to complete the repair, you should seek the advice of a professional.

8 Causes of Your Troy-Bilt Leaf Blower’s Poor Performance

Husqvarna Leaf Blower Gasoline Is Old or Bad

As soon as 30 days after purchase, gas may begin to degrade and lose some of its effectiveness. When gas has been sitting in a leaf blower for a long time, it can become stale and impede the engine’s ability to function.

Most gasoline has ethanol, a biofuel made from plants, added to reduce its environmental impact. While a limited amount of ethanol can be used in most cars, it should be avoided in your Troy-Bilt leaf blower’s little engine.

As ethanol attracts moisture from the air, it can cause varnish and sticky deposits to form in the fuel system, which in turn can block the fuel system and make the carburetor inoperable.

As a result, fuel with more than 10% ethanol content should be avoided.

The fuel needs for 2-cycle and 4-cycle engines found in Troy-Bilt leaf blowers are distinct.

  • Premium air-cooled 2-cycle engine oil and gasoline are the recommended fuel mixture for use in Troy-Bilt 2-cycle leaf blowers. It is a 40:1 mixture of gas and oil.
  • Straight gas is required for use in 4-cycle Troy-Bilt leaf blowers. For these motors, it is imperative that you never combine the two fuels or oils. The engine oil recommended for SAE 30 will have its own dedicated fill point.

Gasoline should be purchased within 30 days of use for optimal quality. Add a fuel stabilizer like Sea Foam or STA-BIL if you need to keep a tank of gas for longer than this before it can be used up.

Here you may learn how to choose the best gasoline for your Troy-Bilt equipment.

THE SOLUTION: Pour the fuel out of the tank into a safe container. Put in some new fuel that has been stabilized. Activate the leaf blower and wait for the gasoline to combine.

A Troy-Bilt Leaf Blower with a Grimy Spark Plug

Combustion cannot begin unless the fuel and air mixture is ignited by a spark. If the spark plug is unclean or damaged, it may only fire occasionally, which will cause the blower to operate poorly and slowly.

An improper electrode spacing or a loose spark plug boot can also reduce engine performance.

Use a spark plug wrench to take out the spark plug. Ensure the condition by checking it. If you see that the tip is very dark, the porcelain is cracked, or the electrode is scorched, you should replace the spark plug.

If you discover that your spark plug is simply dirty, you can either cleanse it with a wire brush or substitute it.

A new spark plug is my go-to because it’s so important to the leaf blower’s overall performance. Make use of a feeler gauge to ensure that the spark plug is at the correct gap.

Put in a fresh or cleaned spark plug and connect the wire to it tightly.

Clogged Fuel Filter on a Troy-Bilt Leaf Blower

It is common practice to install the fuel filter in the fuel tank at the end of the fuel line. Dirt and other debris can’t make it into the fuel system thanks to the filtering process.

If the filter is clogged, it prevents a steady supply of fuel from reaching the blower, causing it to run poorly.

REMEDY: Change out the gasoline filter if it gets clogged. Leave the gasoline tank cover off and place the leaf blower on a level surface.

If you’re replacing an old filter with a new Troy-Bilt filter, double-check its position to ensure it fits properly. Take remove the gasoline filter from the tank.

To remove the filter from the tank, you can hook it with a clean, bent wire around the gasoline line. Using one hand on the fuel line and the ring clip, carefully remove the filter from the fuel line.

Replace the old gasoline filter with a brand-new Troy-Bilt and fasten it securely. Return the fuel filter to its original location inside the tank. If the fuel level is low, it must be positioned so that it remains submerged. In any other case, the leaf blower would be unable to function due to a lack of fuel.

A Troy-Bilt Leaf Blower with a Blocked Fuel Line

Fuel lines in leaf blowers are susceptible to clogging from old gas. Inspect for a pinched or kinked line, or one that has become plugged.

The solution is to install a new gasoline line in lieu of the old one if it is corroded, kinked, or otherwise compromised.

A Troy-Bilt Leaf Blower with a Leaky Gas Cap

Venting air from the gasoline tank to maintain a constant pressure inside the tank can be compromised if the vent gets clogged or damaged. A gasoline tank vacuum can be created if a vent is blocked. It prevents gas from leaking out of the tank.

In order to do so, you need to open the fuel cap of the blower and let some air into the tank. The fan should be turned on and left running.

Keep your leaf blower on a flat surface to avoid leaking gas. To establish the gasoline tank vent is faulty, tighten the fuel cap and operate the blower again to check if the problem persists.

If, after installing the fuel cap, your blower begins acting up and running roughly again, the problem lies in the fuel tank vent, which must be replaced. Most Troy-Bilt leaf blower vents are integrated into the fuel cap, so you’ll need to replace the cap itself.

A Troy-Bilt Leaf Blower with a Clogged Air Filter

If you don’t have enough air, the engine won’t work. It will be difficult to use the leaf blower without sufficient airflow.

A clogged air filter is one cause of diminished ventilation. If you don’t clean and change your air filter regularly, it might get clogged up with dust and other particles.

If your air filter is clogged, the ANSWER is to get a new one. Often, the cost of the inexpensive air filter is little. When it comes to safeguarding the motor, this part is crucial.

Due to the wide variety of filter styles used in Troy-Bilt leaf blowers, it is recommended that you consult the handbook that came with your specific model before attempting any maintenance on the air filter.

There are a number different types of Troy-Bilt air filters, and I’ve included cleaning instructions for each of them below.

Cleanse a Troy-Bilt FOAM primary filter:

  • Take out the air filter foam and put it in the trash.
  • Cleaning the housing and the cover should be done as thoroughly as possible. Keep the air intake free of debris.
  • Use some water and some mild dish soap and wash the foam filter.
  • Take a shower or bath until the water is clear. Rinse the filter in a sink or other container of water and lay it flat to dry.
  • Once the filter has dried, you should coat it with SAE 30 engine oil and then squeeze out any extra oil. Don’t let oil seep out of the edges. Just oil the main filter foam filters if necessary. To avoid clogging the pre-airflow, filter’s replace the paper air filter with an oil-free replacement. It’s bad for the paper filter if you do that.
  • Put in place the open-cell foam filter.
  • The air filter cover must be reattached.

Troy-Bilt Leaf Blower Is Filthy

If you want optimal performance from your leaf blower, you need a carburetor that mixes air and gasoline in the right proportions. When the channels are clogged, the tiny parts stop working properly.

A rough-running leaf blower could be the result of too little gasoline being combined with the air.

Carburetor cleaning can be used to dismantle your carburetor and restore its functionality.

If cleaning the carburetor does not resolve the problem, you will need to either repair it (if rebuild kits are available for your carburetor) or replace it.

Troy-Bilt Leaf Blower With A Clogged Spark Arrestor

The leaf blower’s exhaust is directed through a small metal screen, preventing anyone from being burned or igniting a fire from flying debris. An arrestor for sparks, this screen is here.

In the absence of regular cleaning, carbon deposits will accumulate and impair the engine’s performance.

The spark plug wire needs to be disconnected. Take off the exhaust hood. Gently take off the spark arrestor screen.

Using a metal brush, wipe down the screen and replace it. The engine exhaust cover must be reattached. The wire to the spark plug needs to be reconnected.

A new spark arrestor screen should be installed if the old one is too dirty, broken, or has a hole in it to be effectively cleaned.
