I just wanted to say that I just bought a new dolmar ps540 from Tony Miller and I am very pleased. He was very fair to deal with and his shipping was very prompt. I expressed some concern about carb adjustments when I ordered it from him and he adjusted the limiter caps to give me another 1/4 turn to the rich. Needles to say it was spot on when I got it and it accelerates and runs great. I tested it briefly last night and it is a very easy starting saw and seems to have good torque. I will deal with Tony again and highly recommend him.
