Update on the 261 goes like this: Dropped it off at the dealer and they calibrate/reset or whatever it is they do. Saw runs ok for the next full day of use, still boggy off idle but much easier to start. It has now started to cut out when it gets down to about 1/4 of a tank. I will make several cuts in a row and then it comes back to idle and it cuts out after a couple of seconds like I have hit the off switch. This has happened maybe 10 times now. The next step is going back to 50:1 I guess and see if that makes a difference.
