I figured this saw didn't need one as it's not a pro model.
Partially seized exterior muffler bearing?
I figured this saw didn't need one as it's not a pro model.
So what's left?
Here's what it was:
The plug wire was separated and corroded where it goes into the spark plug boot. I changed the coil with a used one and the saw fired right up and sounds normal. Haven't put a bar on it yet but am convinced that was the problem. This did not seem ignition related to me as the saw would consistently start but was boggy. I'll add that to my diagnostic memory bank now. Put about 5 hours of labor in figuring this issue out. The engine never "clipped" "missed" or cut out like ignition issues usually display themselves, it just ran gutless. If I was starting over, I would suspect compression and fuel. Never thought an ignition issue could feel and act like that.
I had the flywheel off and put it back on. Key is intact.If you haven't run it in wood yet, check the flywheel key. Retarded timing will do just what you described.
