Hello and welcome to Just Answer,


The problem sounds typical of a carburetor that has some stiff diaprams. I would suggest that you have the carburetor rebuilt. I would also repalce all of the fuel lines and the fuel filter as well. Another thing to check is the screen in the exhuast to make sure it is not plugged up with carbon.

this saw is a year old this month with maybe ten hours on was stored when not used with carb you really think i might need a carb rebuild?
Expert:  J.R. replied 4 years ago.
Yes I do. The gas these days is terible on the diaprams in the carburetors. It is common to have to rebuild the carburetors nearly every year now.
