sparkplug

Hey fellas, I opened up my new 445e muffler a little bit (drilled Two 1/4 inch holes and removed spark arrestor) I have the tool to adjust the carb. I believe I have it four stroking and it cleans up well in the cut. After a few hard hours the plug looks pretty lean, if I back the H screw out...

I don't own either of these types of saws but I was curious as to how the plugs look on these saws since they are supposed to be running on the verge of too lean. Pics would be great if anybody has some.
