They may be working perfectly one moment and then suddenly stop running the next. We know how frustrating it is, so we created this article to help you understand the reasons your chainsaw stops running.

Chainsaw Problems: The Most Common Causes

Chainsaws that stop running are most often caused by clogged carburetors, damaged sparkplugs, or flooded engines. It is still difficult to find quick solutions to common problems, especially if you don’t know what caused the engine damage.

: How To Start Problems

Too much tension in your saw caused by fuel buildup can often cause problems. You should still pull the saw a few times before moving on to other troubleshooting steps.

Cold Weather

Machines can become malfunctioning due to seasonal changes in temperature and weather. The machine can be restarted and adjusted by pulling the choke, especially in cold conditions.

: Hit The Throttle For An Extended Period

Chainsaw workers often make the common mistake of trying to hold the throttle for too long or repeatedly. To avoid damaging your engine and causing it to stop, you should not incorrectly hit the throttle.

Chainsaw Running Problems And How To Fix Them

Issue 1: Old Or Bad Fuel

Engine problems can be caused by contaminated fuel. It all boils down to the evaporation of volatile agents, which happens after a few weeks from the machine’s purchase. Blockage of fuel filters makes it difficult for engines not to get enough fuel to run.

Solution: Refuel with High-Quality, Fresh Oil

Replace the oil with new oil if it is bad oil. We recommend that you use a specific ratio of fuel and fresh gasoline to prevent interference with your machines.

Issue #2: Spark Switch/Plugs Problems

Spark plugs are used to ignite combustion, particularly in the area of the air-fuel mixture. They can easily become worn down by frequent use. Spark plugs tend to erode quickly, especially if they are used frequently.

Solution: Look for a bad spark plug

You can check for sparks by touching the metal part of the spark plug with another wire. If sparks are not produced by the electrodes, it is more likely that there is a problem with the plug.

Issue #3: Clogged Or Dirty Carburetor

Woodworkers can be frustrated by a bad carburetor because it will require a costly replacement. It is the part that ignites gas in the combustion chamber. This makes it a vital component of every chainsaw. If you let bad fuel sit in the fuel tank for too long, it can cause the carburetor to become clogged.

Solution: Either clean or replace the carburetor

To keep your engine clean and prevent sticky substances from building up, keep a carb cleaner and a carb kit on hand. A carb kit should include gaskets, O rings, and replacement parts.

A whole carburetor can be purchased if normal cleaning fails to solve the problem.

Issue #4: Flooded Engine

Your engines will flood if you overdo a fuel pump push. A moist spark section is a sign that your engine has flooded.

Solution 1: Drain the fuel

Allow your chainsaw to sit for at least 15 to 20 minutes. This will allow the bad fuel to evaporate. This works best for mildly flooded chainssaws and optimum fuel.

Solution 2: Reset the Carburetor

Different chainsaw brands require different carburetor calibration settings. If the engine does not rev up or reach its maximum power, adjust the high-speed screw. The low-speed screw should be calibrated if the chainsaw engine stops or stalls. Adjusting the idle screws is recommended to ensure proper airflow.

Issue #5: Bad Recoil Startinger

The recoil starter is an essential part of a chainsaw’s engine. Engine stalls can be caused by the spring not recoiling onto the pulley. This is a common error that most users make.

Solution: Replace with a new Recoil Starter Assembly

Broken starter ropes, or one that does not recoil, can be frustrating. Depending on the severity of your problem, a new recoil starter assembly may be the best solution. To ensure you get the correct rewind spring, make sure to check with your local hardware.

Issue #6: Damaged Or Blocked Idle Port

The idleport keeps chainsaws in idle mode. This part can become blocked or damaged over time, making it unserviceable. Your chainsaw will stop working properly if it is not in the idle position.

Solution: Clean the Idle Port or Replace It

Clean the chainsaw’s idle port and idle screw with any solvent, such as alcohol or kerosene.

You should maintain a good idle to keep your chainsaw running smoothly.

You can also clean the spark arrester or small screen with a wire brush. This could be another reason for idling problems.

Issue #7: Fuel Delivery Problems

A chainsaw’s engine will stall if it doesn’t have enough gas. A clogged fuel filter can cause problems when a chainsaw is being run. If the fuel is contaminated and has not been used for a while, this can cause problems with your chainsaw.

Solution: Check the Fuel Filter and Fuel Linings

To clean the fuel filters and fuel lines, you need to dampen a cloth with some liquid with gas or Kerosene. This will prevent the cloth from drying out. Replace the entire fuel line if it is damaged or too bad.

We recommend avoiding ethanol gas, which is a common cause of fuel line damage.

Issue #8: Dirty Or Clogged Air Filter

A clogged filter is another reason your chainsaw will not run. If your air filter becomes clogged, it blocks the air required to burn fuel. This can lead to too much fuel and a depletion in the combustion chamber.

Solution: Either clean thoroughly or find a replacement

Cleanliness is key to any air filter’s effectiveness. Clean the chainsaw’s air filter by thoroughly washing it. Use a bristle brush to remove any stray hairs.

You can wash some air filters depending on your chainsaw model. However, if you don’t like the results, you can get a new one.

Issue #9: Fuel Tank Vents Or Fuel Caps Clogged

The chainsaw pressure must be balanced to allow fuel to the carburetor. Your chainsaw may have vents or caps depending on its model. These should be maintained.

We recommend that you never start your chainsaw without the fuel cap.

Solution: Check the air vent

To check if your chainsaw is stalling, do a quick test. Before you start the chainsaw, loosen the fuel cap. If the engine continues to run, it is likely that the tank is at fault.

Refer to your manual for the correct cleaning steps to take on the air vent.

Issue #10: Clogged Or Damaged Primer Bulb

Primer bulbs enable gas to be sucked into a cold carburator through suctions. The primer bulb is where fuel goes before it enters the engine. It should always be filled up with gasoline.

Solution: Replace the Primer Bulb

Exposed primer bulb material can crack if it is allowed to dry too long. If the air escapes, the chainsaw will not turn on. Replace the primer bulb if this happens.

How To Properly Start Your Chainsaw

Step 1: Place The Chainsaw On The Ground

Take off the cover and place it on the ground.

Step 2: Pull The Brake Chain.

To ensure that the chainsaw bar is not rotating onto the chainsaw bar, push the chain brake forward.

Step 3: Decompress

To get your saw to start, engage the smart decompression key. This smart start button is now available on all new models.

Step 4: Turn On The Fuel Pump

Continue pressing the pump until the fuel is visible to keep the machine running.

Step #5: Take The Starter Rope

Place your left hand on the top of your chainsaw, and your right foot on its handle. Then pull the starter rope slowly.

Chainsaw Maintenance And Care

To keep your chainsaw in top condition, you must follow proper maintenance.

Loose Nuts

To ensure that the chainsaw runs properly, adjust the nuts as needed.

Keep The Blade In Check

To determine how sharp it needs to function, you should inspect the blades after each use.

Keep Your Parts Lubricated

To prevent your saw from heating up, ensure that all moving parts are kept lubricated.

Keep Your Home Clean

To avoid damage from dirt and debris buildups, keep your chainsaw clean.

Gas Of High Quality

Premium gas is good for your chainsaw, but you should use fuel stabilizers to prevent bad fuel from sticking to your machine for too long.

FAQ

Why does my chainsaw stop working when I give it gas

The fuel that is used to damage the engine causes a chainsaw to stall. This is a common problem that can be solved by purchasing extra filters, O rings, or replacement gaskets.

Conclusion

When it comes to power tools, maintenance is key, especially when it comes to chainsaws. We recommend that you spend more time reading manuals to get to know your chainsaw.

Simple dirt can cause engine damage that is irreversible. You don’t want to spend any money on repairs.
