Since I just got "paid" for fixing a MS 460 by being given two parts saws (a 460 and an 046) I am now up to 7 sets of 046/460 cases, 4 tank handles (3 are 046), and 3 cylinders (one has a few broken fins, but I think I'll use it anyway). I may not remove one of the jugs, as the piston seems OK and it has good compression.
The other two are both Mahle, one a D jug, and one a Hemi. I plan to do some measurements for comparison, but the most obvious difference from just eyeballing both of them is the shape of the intake port. The Hemi jug has some broken fins and transfer, the D jug is near pristine. The saw it was attached to was not, so I'm please the cylinder was OK. Muff bolts were "Allen" style instead of T-27, so I feared the jug was not original, but it was. The muffler did not have a cover, but the factory hole on the back half is huge!
I'm really looking forward to putting this D jug on a saw and getting it running. Plan to thin or delete the gasket, and give it a timing advance. Yea, I know, like I need anther saw … but it's a D jug!!! SN started with 136.
