Question and Answers


Husqvarna 445 chain saw stay running


Thank you for your question.



I am sorry you are having a problem with the chainsaw. If you need to pull the choke out to keep the engine running, the likely problem is the passages in the carburetor are partly plugged. When this happens the engine does not get the fuel needed to keep running. When you pull the choke it give the engine more fuel and it keeps running. It usually only takes cleaning the carburetor to cure this problem. I found a great video that shows how to clean the carburetor. Click here to watch the video. The video shows how to take the carburetor apart. Once it is apart you can flush the passages with carburetor cleaner and compressed air. After it is cleaned you can reassemble the carburetor and check the operation.


I hope this is helpful. Please let me know if you need further assistance.



Thank you for using Manage my life.
