Well, I bought it. The guy shows up and tells me it'll run, 'cause there's still fuel in it. I ask how long since he ran it last, says a couple of years. Ugh! So I dump the turpentine, add fresh fuel and yank away. Nope, not gonna fire. Didn't expect it to anyway, but I had to put on the show. Pulled the plug at his insistence, looked new. He thinks the problem HAS to be a bad plug. And so it goes, but I did get him to knock $20.00 off his asking price. This is the older version of the 346XP, orange side cover, so not the saw he had listed. But the thing is basically brand new. The chain is dull, but the bar hardly looked used, paint was hardly scuffed. I just dropped it off at the Husky dealer, and he's gonna clean the junk out of the fuel system, but he told me the thing looked new on the inside. He was impressed. So, I have to learn about the older version of this thing, 'cause the balance and weight are fantastic compared to my 455. Does this thing have a CAT muffler? and if so what can be done about it? Or should I leave well enough alone and enjoy the saw as is? If it was YOU, what would you do to the saw? Thanks, JB
