Your Chainsaw Won’t Start When It’s Hot Here’s Why

There are a few reasons why your chainsaw might not start when it’s hot. The most common reason is that the carburetor is flooded. This can happen if you choke the chainsaw too much or if you let it sit for a long time with the choke on. Another possibility is that the spark plug is fouled. This can happen if you run the chainsaw out of gas or if you use the wrong type of gas. Finally, the air filter could be dirty. This can restrict airflow to the carburetor and cause the chainsaw to run lean.

In this article, we’ll take a closer look at each of these potential causes and discuss how to fix them. By the end, you’ll know how to get your chainsaw started again, even when it’s hot.

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 and not enough air. This can happen if you choke the chainsaw too much or if you let it sit for a long time 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 means that the electrodes are covered in carbon deposits. This can happen if the chainsaw is not properly maintained or if it is used in dirty conditions. To fix this, remove the spark plug and clean the electrodes with a wire brush.

The air filter is dirty:
A dirty air filter can restrict the flow of air to the carburetor, which can cause the chainsaw to not start. To fix this, remove the air filter and clean it with a brush or compressed air.

The engine is overheating:
If the engine is overheating, it will not start. This can happen if you are using the chainsaw for too long at a time or if you are using it in hot conditions. To fix this, let the engine cool down for a few minutes before trying to start it again.

What’s Causing the Problem?

There are a few possible reasons why your chainsaw won’t start when it’s hot.

The engine is overheating:
If the engine is too hot, it can cause the spark plug to foul, which will prevent the engine from starting. To check if this is the problem, let the engine cool down and then try starting it again. If it still doesn’t start, you may need to clean the spark plug.

The carburetor is flooded:
If the carburetor is flooded, it can also prevent the engine from starting. To check if this is the problem, turn the choke off and try starting the engine. If it still doesn’t start, you may need to clean the carburetor.

The fuel filter is clogged:
A clogged fuel filter can also prevent the engine from getting enough fuel, which can make it difficult to start. To check if this is the problem, remove the fuel filter and inspect it for any debris. If the filter is clogged, replace it with a new one.

The air filter is dirty:
A dirty air filter can restrict the flow of air to the engine, which can make it difficult to start. To check if this is the problem, remove the air filter and inspect it for any dirt or debris. If the filter is dirty, clean it or replace it with a new one.

How to Fix the Problem
