Okay, so what is the worst thing that can happen to your saw, by running it to rich, besides loss of performance.
Fouled plug, clogged screen in muffler, Excess deposits in exhaust port and top of piston, killing mosquitos around cutting sight LOL
Glad you understood the question.No no, you guys are mis-understanding. Re-read the original question. It's not "too" rich, it's "to" rich. So running just on the rich side of perfect A/F ratio. That's pretty much where I run all of my saws.
So where is the best balance. I have tore down saws with huge carbon build ups in the exhaust port, thin coat on piston and combustion chamber.

Last one like that was my Jred 52. I just cleaned the exhaust port out haven't pulled the cylinder but will when I do the bearings. Piston looked like new from the exhaust and blew a solid #160.
But the build up was somewhat alarming. Not just a coating but little pencil eraser sized chunks on the floor.
I envisioned a chunk breaking loose and getting sucked back into the cylinder.
Is this more fuel mix quality related then A/F ratio?
