I'll give that a try. I hope to have time this weekend to run a few logs and make some small changes to see if I can eliminate or at least move the surging again to perhaps figured out what I am changing to remove it from certain spots and hopefully eliminate all together. When it does it now, it almost feels like a manual transmission when you go on and off the throttle. About every second or so I can feel on-off-on-off-on feeling. The lower rpm stuff seems to be really good now, but the 2000-2500rpm when gently cruising seems to really buck now. Bucking is a better word for it lol!. Thanks again.
