Up for sale is my Mastermind ported 592xp. $1,200 plus actual shipping from 28105. This is a big, well ported saw and performs as it should. I replaced the original muffler with the newer, beefed up version. The inner spike dog mount broke a year or so ago but I had it mag welded with no issues since. I've always ran it with echo red armor at 40:1 with ethanol free fuel. There are no issues with the saw that I know of. Steve.
