Is the mille a dual-point system?

IIRC, on my dual points I undid a screw on the advance plate and popped he points out as a unit. There was no disassembly involving a circlip (although I know the kind of '2-piece' points that do disassemble from a fixed post). But I have not contemplated a MM distributor in years, so my remembery may be impaired.

You might look at a new set of points to save time.

So to clarify -- this is a points mfgr problem, not a distributor wear problem?

Any idea what the part number is on your points? Same as all the other earlier dual point distributors?

My quick fix would be to peen the post into place.
