No, I have not, but have to start somewhere. Saw is oem, never really used much, never really had any problems other than brake band was broken for not knowing how to put cover back on years ago. Always used for limbing when it has been used. It runs great, cranks on second or third pull, it screams, idles as long as you want it too. I'm new to the site, and I am a big fan of the Sachs Dolmar saws. I have always used a few professional husqvarna saws - older ones, but have begun converting over to Dolmar. Will probably always keep my 2 - 272XP saws.. Its a good 254 chainsaw.
