We waited til after xmas so saw arrived today. All seemed in order so I fueled it up. Started on 8th pull. As it warmed up it started to race so I shut it off. Cold dense air so I did not even try to tune while running. I backed off the idle and turned the H to full rich. Started it up and it idled just right. Let it warm up and made a few cuts. Ran good but bogged when worked hard. Backed off the H a quarter turn and it ran great, losing very little rpm in the cut. Good saw. I know Jim does not need my feedback to validate his saws, but I hate it when these threads end and you have no idea what happened. Good saw and Jim was easy to deal with.
