I'm looking at that green fuel cap...is it a catalytic muffler saw.

It surely was the E-tech (cat) saws that come with them - but often the cat has been "relocated" and/or the cap has ended up on another saw.
The E-tech saws also said "E-tech" in small print on the label of the starter cover, and it doesn't look like that is the case on that particular saw, indicating that either the green cap or the starter cover is not original to the saw.

Looks to be a g model as well.

Most of them are over here, very few buy a pro class saw without heating.

         That last 346 is the one I converted from a 353G model.   I do most of my wood cutting in cold weather and helps keep my hands warm.   No CAT on this saw.  That was the 1st thing that came off .   The green cap will come off someday I guess.  I don't mind it all that much.   Farthest thing on my mind when I run this saw.

Of course you don't mind that green cap when you run the saw, but I certainly would when looking at it.

Btw, cat mufflers originally were made for "operator environment" some time in the 1990s. It mainly was Husky and Stihl that did it back then, and both admitted it reduced power and increased weight slightly.
At least over here you had to pay extra for it - but at a point (around 2007 or so) it turned into an EPA thing in the US - and it still is used for that in the US, although not by Husky or Stihl - that use the "strato" technology instead.

It may look odd that some brands (like Echo and Chinese saws in general) gets away with not using either - but I suspect that's about the very low power output of most of their saws, which usually means less fuel is consumed.
