hello all, I have been reading threads for a few months. This is my frist. I have a 066 that I use for milling and I would like to get more power from it. Is there any thing I can do myself to improve chain speed and power? I'm one of those guys that likes to do stuff my self. Not to save money but for self satisfaction.I'm a perrty good auto tech (if that has any bering on chainsaws)not for living but part time.I wellcome all appinions and input. Thanks
