Hey, no problem hope it helps. If you need more help consider this:
A trick with model engines I used, pinch fuel line to starve of fuel at idle. If engine speeds up and dies than you're at a good tune. Should be a noticeable change, no change at all than too lean. This works for checking tune at idle pretty well. With a saw could listen to it as it runs out of fuel or needle nose pliars reach in to pinch line.
Remember when you richen the oil/fuel mix with more oil, you're going to richen carb. I don't recall on mine how much richer than factory I'm running. Want to say around half a turn on both. Had the limiters set so they'd stop at the perfect tuned and left plenty of room to richen more. Easy to get things back that way, than one day I couldn't get it leaned enough so had to reset it, think I switched oil brand.
Youtube vids are great from reputable source, just remember "fat is where it's at", LOL. AKA, just a tad rich. I hardly every touch my carb and I mill off an on all yr. Some days it could be small tad richer or small tad leaner, but still in the range of an ok tune. I think when you tune more on the lean side you run into having to adjust more often. Don't forget you'll lose power when you get too lean just like too rich. Shoot for the middle. When you check for in the cut, make sure you've go something big enough that'll actually load the saw. I mentioned can barely tell in some soft woods or small logs. If that's all you mill than tune for that, but mine only really just but steadily sings in med large logs.
When I'm not milling, my saw doesn't quite have the power or snap to it but I don't bother to re tune as it's mainly a milling saw where it runs a perfect tune for that loading. It does cut ok, just ever so slightly noticeable.
