Hi guys, new here. I have a old Jonsered 670 I used to run for many years. I have new saws and want to build it for power and longitivity at the same time. I need input as far as what all I can do to squeeze max power out of it. If I remember right all I have ever done is install a new stock piston and rings. Should a guy go with a new rod/crank assembly? Where do I start?
