I have an Echo blower that idles fine but cuts off when i open the throttle.

I have cleaned the carb well but still no joy.

I wanted to check the in-tank fuel filter but it seems hard to get to. I didn't do it since I figured that it was fine since it idles fine. I also adjusted the H and L settings but it still has the problem.

Any ideas why it just won't run with the throttle open?

What is the model of your blower?
