how can i fix my echo gas blower model PB261L?

MY blower just is'nt blowing right! When i give it gas it just sounds like its bogging out and is very weak when it comes to blowing. i've changed the gas filter and air filter but not luck in making it blow like it can or use too. please someone help.

First thing to check is if something has gotten into the fan and is restricting the fan from turning like it should. If it is clean then use fresh gas instead of the old stuff you have. If still no success then adjust your carb screws. Small turns to the right while it is runing
