Hi - Wouldn't ya know it, my first post - & my 1st question.
I'm about to buy a Mallory dizzy - butt
I'm having a 'lil issue trying to understand how to fill in the blank when choosing what idle & total advance to answer for one of the questions when I attempt to buy the Mallory dizzy p/n IGD003 from a/c. The a/c Q is;"We will install the springs of your choosing (normally grey/grey), and setup the centrifugal advance curve to your request. You must tell us what idle and what total advance you want in the special instructions field, when you checkout."

Well *&%$ I don't know! I do know that it's for my '73 914 2165cc TYPE IV daily driver. HELP!! What numbers give good low end torque & street mileage??? I'm stumped:?:

Thanks, Gary

Grey/Grey, 12-28 and VACUUM ADVANCE (for street use) will provide a decent starting place.

I own several Mallorys:

They all now live in a box, late stock hall effect ignitions live in the cars, the stock dists are very easy to recurve, and (I hear from a little bird) the Mallorys have problems lately with QA/spark scatter.

The mallorys are great distributors. But....also like Piledriver I have beenfinding creative and dependable ways to upgrade with stock distributors.

Since I play so much with D-jet....the choice was down to loading my modified D-jet trigger system into a mallory (not all that hard, but tedious) or improving the stock model.
I found that with a few choice maufactured parts like a pair of Torlon bearings...and some weights, springs, bushings and shims scavneged from late model Bosch electronic dizzys....I can achieve several hundred percent better specs., adjustability and performance.

Think of it like "blueprinting" an engine...only its a distributor. If you know what tolerances a distributor has...and where you want it to be...its not that hard to modify what you got. Ray
