Thanks!
Thanks to you all for a warm welcome!
To answer a few of the points mentioned, yes I think that I probably will end up with some other saws as I go along. I recognize the CAD propensity, and I am easy prey to the same kind of disorder in many hobbies. I have eaten my share of Noodle Ramen while saving to buy things that I really didn't "need". But it's fun.
I will do a lot more reading on tuning and maintenance, so that I can keep the saw in top shape. I appreciate the tips that some of you here have already given. I will use non-ethanol gas, and my initial plan is to use the Stihl pre-mixed 50:1 fuel. I do have a non-ethanol source at a station near me, but it's 87 octane, and I doubt that it's sufficient for the high compression in this saw. So, while the source is there at the pump for 87 non-ethanol, I would feel better spending a bit more to get the canned fuel at the chainsaw store downtown.
Regarding the muffler with the cat, I will use it for the time being as it is, and see how I feel about it.
I discussed it with my dealer where I bought the saw yesterday, and he said that if I want the non-cat muffler for a 5100S, he would install it and re-tune, including over-riding the limiter caps if necessary, for about $50. And he told me that if I had him do it, that it wouldn't void the warranty because he'd stand behind it. So, that option is available for me if I want to do it.
He said that this 5105 model runs so strong that he doubts that I will feel the need for any more power out of it. But, we'll see. I'm a hot-rodder at heart, and it rarely has anything to do with "need". After the warranty is up, I might even look at getting it ported.
I have a lot of stuff to do this week-end, but I'll find some time to cut something down with this new saw!
