Lou:
Thanks for advice, it's good to know, I am always careful when I adjust carburetor, at least from when I started doing it myself (not so long ago), but mostly I adjust idle screw on the chainsaw, other screws I put on factory settings, because the chainsaws are old, and not modified, or I take it to the official chainsaw repairing service.

Thanks for advice, you were right there was some oil, probably leaked or spilled by me when I was filling the oil tank. As for the boiled fuel mix, there is possibility that was issue, but I don't know neither what caused it because, as you said the 'saw wasn't that much warm, I think I saw on some other post that same problem and if I recon well it was problem with fuel vent system. Also, when I started the 'saw next time, with the L screw on "sweet spot" as you called it, it was idling, and working without any problem, I was surprised, but that wasn't the end of my surprise.

Thanks for advice, I'm sure that carburetor came with chainsaw from factory, and it's Tillotson. On it there are numbers 15 006, at least that's what I read on it. I didn't changed anything yet on it, because I found recently on the internet that, I can order new carb kit (as recomended on Mr Mike Acres's site) directly from Ireland or Italy, but because of this bad situation with Corona Virus, they not ship it outside of the country or outside EU, so I'll wait until this situation ends. I don't know why the L screw on this chainsaw (1 full turn out) is giving best working condition of the saw. Also on some pictures I posted earlier in this thread you can see only 2 screws the lower is the L (and is marked on the hub of the saw, and higher is I presume LA/T screw a.k.a. idle screw but it isn't marked at all, and it's screwed all the way in).
As I said already I succeed to start Pioneer P26 'saw again, and I was surprised when it started to idle and work good, a minute or so. I shut it off, and started it again, first pull, what a surprise, but that wasn't the end of it. I left it to idle a little more, until I feed my dog, but when I turned my back on it, it started to speed up like it was without fuel (it wasn't). And before I got to it, it shut off. I have left it to cool a little and then pulled of the muffler, I saw a little lines on cylinder but not on the piston, I decided to open the cylinder (take it off). It seems that cylinder is damaged, piston and ring not that much, I assume that was from air leak somewhere in crankcase, but I'm not sure? I'm not sure what I'm going to do now.
