If you look closely

I think the one on the right has been skimmed (the lack of the bottom of mahle gives it away) I just hope it’s not been belt sanded
I didn’t time them as I was just tearing them down.

I did notice both had base gaskets. So I’ve got to pay attention when assembling them regarding the squish
I’ve no idea of the history of these saws but both had pto bearings go poop.
And I’m not really wanting to use the crank from one of these saws again. Unless you can convince me otherwise

I do have other pics but this sums it up.

Edit. I should have shown the other side (pto)
