How to Repair A Flooded Chainsaw

by JEREMY HIPA 24 Aug 2022 0 Comments

Chainsaw flood is a common problem for professionals or home owners. We have concluded the reasons, symptoms and solutions for a flooded chainsaw you need in the article.


1.People keep pulling the chainsaw over with stroke on. Because they think they are trying to start and it need more choke.
2.Sometimes some chainsaws end up being flooded because they had a bad spark plug and they keep pulling. It will burn the gas that is building up in the cylinder.


One of the symptoms of badly flooded chainsaws is that they won’t start.
Another is that you might smell fuel and gas or you might see some gas pouring out of the air filter or the carburetor area.
The third symptom, coming in when your chainsaw is excessively flooded, is the chainsaw might be hydrolocked which refers to you may feel like it is jammed when you pull it over. Because there is so much fuel in the cylinder, causing a hydrolock effect to prevent you from pulling it over.


Solution 1
If you've flooded your chainsaw, the first thing you need to do is to stop pulling it and turn the choke off.
The next thing is holding the throttle wide open and obviously making sure the switch is on.
Then keep the throttle wide open and the choke is off. And you just need to pull it over until the chainsaw starts. It is normal if you smell a lot of gas and see there is some fuel on the muffler during the procedure.
As soon as you start hearing it sputter, it means it is starting to unflood itself. Once the chainsaw starts up, it is going to burn the fuel on the muffler off.

Solution 2
If your chainsaw is hydrolocked, you need to follow the steps below:
Step 1: First of all, you need to make sure the switch is in the off position.
Step 2: Take the air filter cover and the spark plug off.
Step 3: Keep the spark plug boot away from the spark plug hole and then pull it over until the gas sprays out of the spark plug hole. You may want to put a rag there to catch the gas from springing out onto your face or all over the place.


If your chainsaw keeps flooding after you’ve unflooded it, you may have to do some carb work to it. And sometimes if your fuel tank is not venting properly on your chainsaw, it can create a lot of pressure in the fuel tank that in turn will push too much fuel to the carb and the cylinder, even when you are not using the chainsaw.
It is important to make sure you have a good spark and not to have too much fuel in your carb.
