How long have you had the 540? I ran a ton of 200's, tried a 540 when the first 201s came out and sucked. The 540 ran like crap and wouldn't run and had many issues as well as being weak and getting broken. I traded it in to recoup what I could against a 880, sweet saw. I then went back to the 201 and since stihl sorted them they are imo the best new tophandle out there.
