PM 310 and 320 same saw???

[MuleyJ]

I was given an old McCulloch pm 310 by my father in law and have it running pretty well. I have been looking for a parts saw or two online. I have run across a few 320's along the way and they look to be almost exactly the same. They spec pretty close to the same on a web site I found. Would the parts on these two saws interchange? If not what are the differences?Thanks everyone.

There is a small difference in displacement. But if you took both the 320 piston and cylinder they would bolt right onto a 310. As long as you didn't mix a 310 piston with a 320 cylinder.

Every single other part will interchange.

The difference between a 310 and a 320 was the 320 had Auto Sharp otherwise their the same saw.
