This is a handyman offer. As you can see in the picture this chainsaw is apart with a bad trigger switch (part # 530025518). I pulled the switch apart and cleaned everything but putting the switch back together has "tested" me. I already have several corded chain saws (which I love when within range of house or gen power. No dead batteries or gasoline fumes) so I have no need to push this repair further.
A new switch is no longer available. Maybe a used switch from a local repair facility like Fulwider, put this switch back together or jury-rig another switch (safe??).
I'll wait a couple of days and then it's into the metal recycling hopper.
