Hi Mike,

Jeff converted my DM2 distributor to 25D about a year ago. It DID make 
an improvement. Actually, I just kept my old distributor & he furnished 
a well rebuilt assembly.

The original DM2 advance mechanism is a very strange design with center 
pivoted advance weights. The timing was erratic over the rpm range, not 
just slow to return. The 25D is  much more conventional & in my opinion, 
more precise & repeatable. Jeff tailored the advance curve to my 
requirements & did excellent work in building it.

I can't say whether the later points would be an improvement or not. I'm 
using a Pertronix ignition.

Regards,
Dave Russell
