Why Won’T My Chainsaw Start When It’S Hot
Why won’t my chainsaw start when it’s hot?
There are a few reasons why your chainsaw might not start when it’s hot.
The carburetor is flooded:
When the carburetor is flooded, it means that there is too much fuel in the carburetor bowl. This can happen if you choke the chainsaw too much or if you let it sit for too long with the choke on. To fix this, turn the choke off and let the chainsaw sit for a few minutes. Then, try starting it again.
The spark plug is fouled:
A fouled spark plug can prevent the chainsaw from starting. To check the spark plug, remove it from the chainsaw and look at the electrode. If the electrode is black and oily, it’s fouled and needs to be replaced.
The air filter is dirty:
A dirty air filter can restrict the flow of air to the carburetor, which can make it difficult to start the chainsaw. To clean the air filter, remove it from the chainsaw and rinse it with warm water. Then, let it dry completely before reinstalling it.
The chainsaw is out of gas:
Make sure that the chainsaw has plenty of gas. If the chainsaw is out of gas, it won’t start.

What’s Causing the Problem?
There are a few possible reasons why your chainsaw won’t start when it’s hot.
The carburetor is flooded:
When the carburetor is flooded, it means that there’s too much fuel in the engine. This can happen if you’ve been running the chainsaw at full throttle for a long period of time, or if you’ve been using it in dusty or dirty conditions.
The spark plug is fouled:
A fouled spark plug is one that’s covered in carbon deposits. This can happen if you’ve been running the chainsaw at high RPMs for a long period of time, or if you’ve been using it in dusty or dirty conditions.
The air filter is dirty:
A dirty air filter can restrict the flow of air to the carburetor, which can cause the engine to run lean and eventually stall.
The fuel filter is clogged:
A clogged fuel filter can restrict the flow of fuel to the carburetor, which can also cause the engine to run lean and stall.
The engine is overheating:
If the engine is overheating, it can cause the spark plug to foul and the carburetor to flood.
How to Fix the Problem
Once you’ve identified the cause of the problem, you can fix it by following these steps:
If the carburetor is flooded, turn the chainsaw off and let it sit for a few minutes. Then, open the choke and pull the starter rope until the engine starts. Once the engine is running, close the choke and let it run for a few minutes to clear out the excess fuel.
If the spark plug is fouled, remove the spark plug and clean it with a spark plug cleaner. If the spark plug is damaged, replace it with a new one.
If the air filter is dirty, remove the air filter and clean it with a clean, dry cloth. If the air filter is damaged, replace it with a new one.
If the fuel filter is clogged, remove the fuel filter and clean it with a clean, dry cloth. If the fuel filter is damaged, replace it with a new one.
If the engine is overheating, let the engine cool down and then check the cooling system. Make sure that the cooling fins are clean and that the radiator is full of coolant. If the cooling system is not working properly, have it repaired or replaced.

The best way to avoid problems with your chainsaw is to perform regular preventative maintenance. This includes:
Cleaning the carburetor and spark plug regularly:
Changing the air filter regularly:
Changing the fuel filter regularly:

How do I fix a flooded carburetor on a chainsaw?
To fix a flooded carburetor on a chainsaw, you can try to clear the carburetor by removing the bowl and cleaning it with a carburetor cleaner. You can also try to adjust the carburetor’s float level.
To remove the carburetor bowl, you will need to find the carburetor on your chainsaw. The carburetor is usually located on the side of the engine. Once you have found the carburetor, you will need to remove the bowl. To do this, you will need to locate the bowl’s mounting screws and remove them. Once the screws are removed, you can lift the bowl off of the carburetor.
Once the bowl is removed, you can clean it with a carburetor cleaner. To do this, you will need to spray the carburetor cleaner into the bowl and let it sit for a few minutes. After the carburetor cleaner has sat for a few minutes, you can rinse the bowl with warm water.
After the bowl is clean, you can reinstall it on the carburetor. To do this, you will need to line up the bowl with the carburetor and insert the mounting screws. Once the screws are inserted, you can tighten them down.
Once the bowl is reinstalled, you can try to start the chainsaw. If the chainsaw still doesn’t start, you can try to adjust the carburetor’s float level.
To adjust the carburetor’s float level, you will need to find the float. The float is a small, metal arm that is located inside the carburetor bowl. Once you have found the float, you will need to bend the float up or down. Bending the float up will increase the float level. Bending the float down will decrease the float level.
Once you have adjusted the float level, you can try to start the chainsaw. If the chainsaw still doesn’t start, you may need to take it to a qualified service technician.
