What is wrong with my chainsaw? I have a husqvarna 455 rancher. When I squeeze the throttle to full the engine?

When I squeeze the throttle to full, the engine bogs down and dies.

    1, carb too lean,adjust counter clockwise slightly
    2, run at half choke if better do #1 if not go to #3
    3, fuel pump or diafram needs replacement,
    4, spark plug replace? maybe do this first.
    5, clean gas line? n leaks where air is getting in?
