I am not a chain saw guy but I am in a hobby that uses similar 2t motors. The motor I play around with are Zenoah or Chang Yeng short CY but there are other motor out there as well. I would love realy love to learn how to port my own engines for better performance but most importantly I just love to learn new things. I do have a rough idea of tools req for the job also roughly how to port do's and donts but I would love to hear more form you guys. I know there are a lot of info on this forum and if some one could please link some of those threads I would appreciate it.
