Echo PB-403T backpack blower issue
I've got an Echo PB-403T backpack blower that is exhibiting a problem. As I throttle it up, it "accelerates" (for lack of a better term) until it gets to a certain point at which time it seems like it wants to choke itself off. Before I took it apart and replaced the spark plug and cleaned the carburetor, it actually would choke itself off when running wide open. I can get it to a certain speed, but anything after that and it wants to die.
