I recently purchased this saw as a replacement for my MS180C and 029 saws. Nothing particularly special about this MS261 other than the fact that it is one of the few with the typical carburetor versus the electronic M-tronic carb. I had read several reviews about the M-Tronic equipped MS261,and apparently there have been complaints about it's performance under certain circumstances;plus,I don't like the procedure of letting it idle for 90 seconds so it can 'sniff' the atmosphere to make it's adjustments for the day's work. These regular carb MS261's are somewhat scarce /not well known,one Stihl dealer told me they didn't exist and the other dealer was able to get only two of them(he kept one for his collection). He asked why the limit and Stihl told him that there was a very limited quantity to be distributed amongst the dealer network.Go figure.... He summed it up nicely when told me " Sh!t,I don't know whether to use it,bronze it or Ebay it!!" LOL
I have yet to use the saw,but am looking forward to it,as it is light(magnesium case) and has the de-compression valve.
