Another Timing Question

[firefighter3931]

I actually called them yesterday and the guy I talked to didn't know. 

Why is that not surprising 

Dave, give Mancini racing a call. If they can't give you an answer, i will find out for sure from a buddy who works for MP.

I called them again and talk to the same guy (Evan).  He said they weren't sourced from Mallory but wouldn't divulge the manufacturer.   I'll try mancini.  Thanks .

Dave, if Mancini can't give you an answer, try contacting this guy. Rob worked as an engineer for Mallory before starting up his new business. He will have the answers.

Ps. I sent a message off to my buddy at MP...we'll see what he has to say

Ok, just got a message back and here's the scoop :

For the last 3-4 years, MP has been using the Mallory advance mechanism in their MP distributors. Dave, your's might have the Mallory mechanism allready installed given it's age. You need to pull the relucter and breaker plate off to see if there are any torx screws underneath. The torx screws can be adjusted to limit the mechanical advance and there is no kit required per say, unless you want to speed up or slow down the curve with lighter or heavier springs.

I'd have a peek underneath to see what you've got before ordering anything. 

Fwiw, i haven't used one of the newer style MP distributors and mine is an older model with the welded up plate. My next MP dizzy will be a whole lot easier to work with, though.

The guy I talked to said the newer style dist would have an allen-head screw underneath the rotor that would change the advance rate.  He said that both today and yesterday when I talked to him.  Not saying you or your buddy at MP are wrong, just wondering how both scenarios could be correct.  He also said if there was no allen-head screw under the rotor that it was an old style unit.  Maybe there's a third style of dist now?  Who knows.  I've already ordered another one at this point and I guess I'll just have to be POd if it's the same dist I already have.  I'll let you know how things work out.  Thanks for your and everyone's help to this point.

Then again, the guy you talked to at MP also knew nothing about Mallory.
