The MM1 should have a 5/16-18 LH thread on the clutch. I have clutch assemblies and/or parts available.
Assembly is 83906 ($7.95 + shipping)
Spring is 63958 ($3.00 + shipping)
The 110, 120, 130, 140, EB models etc had a straight bore clutch held on with a nut. I think the nut is 5/16-24 LH but don't trust me on that one.
There were at least 8-10 different clutches used on the small saws even though the same drum works pretty much across the board. Two and three shoe clutches, zinc or steel shoes, straight bore and threaded (with and w/o a hex), and several different thread sizes and pitch including some M9 x1.5 LH which it totally odd.
