i have a husqvarna 40. it runs fine at full throttle, idle, but it bogs down and will die once you start cutting with it. does anyone know what the problem might be?
If compression and fuel mix are good:
You might check air filter,fuel filter, and condition of fuel lines & spark plug.
I have a Poulan Pro 260 I found some trash in carburetor inlet screen
causing a similar problem.
