From what I have come across I agree with the folks advising a bigger cc saw. But there are a couple of reasons. First is, if you are going to spend the money get the most capable saw you can afford. If that’s 50ccs then yes, you can make it work. But if you can get a larger saw, then get the more capable tool. Second, I realized a while back that bucking anything with a short bar is not fun. So I started using bigger saws that can handle at least a 24 but preferably a 28 inch bar. Granted, I run old Mac 10-10s with a 28 and they do the job but I have also done some work to the ports and changed the timing. If you don’t want to get that deep, then get a 60cc saw so you can run a larger bar. There is just no way around it unless you want to nurse a smaller saw and a smaller bar to get the job done. A smaller saw will do it, but it will be a slow and frustrating boat the China.
Either way, we all hope it goes well for you
