A coworker of mine has a EFCO 952 that he is wanting to sell. I can get it for $50. How hard is it to get parts for these saws? I've looked through the forums and google and it doesn't seem easy to find info or parts for these saws. Is there any must do Mods for these saws or easy Mods? The coworker says he has put a new cylinder In the saw due to issues he had. From what I've found there are different names for this model? Is a 952 the same as the 152? If so does all the parts interchange? Thanks in advance for any information.
