100M Distributor Question

[TodE]

I am in the process of a restoration on a 1955 100 to Leman's specs. Since I missed the original M distributor on Ebay for $900.00 and some dollars (Wow! Nobody said this was going to be cheap!) I am left with plan B.

Buy a new 100M distributor from Moss or Victoria. Have my 100 distributor rebuilt to M specs or somebody told me that with our gas today a "M" dist. would not run very well and to have the 100 dist. rebuilt with BJ8 curve?

I talked to Tom Kovac's and he stated he has have no promblems with "M" distributors.

Any thoughts on this or mayby somebody might have a NOS, NIB "M" distributor just lying around that I could trade my wife for! Thank you in advance for your help.

Hi TodE,
Got a M spec dizzy as well as a stock one, from memory its the same as a stock BN1 dizzy, ie a Lucas DM2P4 with different springs and weights, and a different vac setting being the only difference, is a place in UK will reset yours to M spec, and mine has no probs with todays gasolines

The DM2 distributors have a very strange toggle type centrifugal advance mechanism which has no positive stop, & is not very precise or repeatable. The maximum advance range often goes far higher than safe for these engines.

This advance can be converted to the later 25D advance which is much more accurate. For a reasonable fee, Jeff will convert your distributor internals to the 25D, completely rebuild it, & tailor/calibrate the advance curve to your engine's requirements. It will cost far less & work far better than a NOS original.

He could also supply a modified distributor so that if for some reason you wanted to keep the original, you could do so.
