I was thinking about the BB kit but haven't heard alot of good reviews about it. Does anyone know of a after market cylinder and piston kit for a stihl 064 I have looked at several sites and can't seem to find one if anyone has any info I would appreciate it as I have the saw down and wanting to put i back together stihl has it but it is close to 300$ hope to find a after market kit. Any info would be great Thanks
