Ok, update time, and boy am I embarrassed! These Huskies sound quite a bit different that equivalent Stihls, so I am going to have to retune my ear as much as the saw.
Threw a tach on it, fired it up. While idling for warmup, it was showing 2700 rpm. So far, so good. After it was warmed up, I gave her a very short full throttle run. 10800 rpm. I thought to myself, "that can't be right." So I did it two more times, and both times got 10800 rpm. So I grabbed my screwdriver and turned it in bit by bit, and checking the rpm each time. Finally hit the limiter tab on the lean side, and all I could get was 12800 rpm.
I dragged a couple chunks of 12" wood home to do test cuts. I sunk the saw into one, and I must say, it was running much, much better. I was actually able to lean on the saw a bit without it bogging.
I think I will leave it as is for another 5 tanks or so. If there are no problems, I will trim the limiter tabs, and, if I feel the desire at that time, open up the muffler. I will also keep the tach in my toolbox until I can get my ear retuned.
The thing I don't understand is why the dealer let the darn thing out of their shop running that rich. I am kind of impressed the thing was running as well as it was. My 260 would have barely run that rich.
Thanks again for everybody's help, in spite of me making much to do about nothing.
