Newbie help with tuning

Yeah I've thought about it but I'm afraid with my luck I'd roast them.

If I didn't have bad luck I'd have none

Something that helped me and I still do from time to time is video tuning and a cut. Then listen back to it, it's much easier to hear the tune when you can focus only on it and not everything else that's going on.

I second this -- I can hear 4 stroking so much better in a video than I can live.

Also -- when someone else is cutting or piss revving from about 10 feet away or more, my ears will zone in so much better on 4 stroke sounds than when I'm the operator. Try having a friend run the saw and back away quite a bit and listen. I also enjoy listening to a 2 stroke w/ muff mod when I'm a bit of distance the louder sound is music to my ears.

Best sound to date was Lee Harvey's bored out Sachs Dolmar 166 at my property which is in the woods the echo off the trees was some of the coolest saw sounds I've ever heard

Ok so I have tuned the 660, even at right off full out (counter clockwise) with a touch back she is still turning 13,400-13,800.
After a full tank of ethanol free 50:1 the serial number right off the side of the muffler is covered in soot/carbon to the point I can't read it.
Just seems rich, but it's turning pretty high still. Cleans up it the cut, blubbers out of the cut.

The 461 in the same spot (on the h adjustment) still hits the limiter, but it doesn't seem to be putting off any soot/carbon.

Seem normal?

You're gonna have to pull the limiters. I pulled mine on my 461. After it broke in, it was too lean. I pulled mine, cut the tabs, then reinstalled. They help steady the screw as there's no spring on them.

Look at the spark plug.

Edit on this chart you want to be "Rick but ok". Sorry it's for a regular 4 cycle. In other words if it looks like a Hershey's bar or a little lighter, perfect.
