I don't think it was stupid to buy the 562 the coil and carb aren't cheap and it just more great content for your channel and it's nice to be able to compare saws side by side.
Long as the case's are same it will work. Probably same size Crank if so just one is full . I doubt be much difference in performance that you'd actually notice.
Hello, if you want to make a 555 to beat the 562 you can swap all the parts, is not going to be able to make no difference 562 can't be defeated, y have tried with my 560,heere in Europe
