Default Actron Timing light

Anybody know anything about this light? Will it work with a MSD distributor? I have heard that some of these do not. This one is in the Summit Racing Catalog and I believe that I need a dial back unit as I am going to disconnect my vacuum advance on my 32. I can't get the timing set with the inductive unit.

Thanks for any help.

Steve:

I do not have any experience with the Actron timimg light you mentioned, but if it has an inductive pickup, I see no reason it shouldn't work.

However, if you have a tachometer and a standard timing light that works now, you can do what we did years ago before dial-back lights were available: make a timing tape to degree your harmonic dampener. If your engine is fairly common, Summit or Jegs may even sell the tapes separately. Otherwise use a tape measure or a piece of masking tape and put it around the dampener to get the exact circumference. Then measure that length and divide by 360 to get the distance for each degree of advance. Then make yourself a timing tape and attach it to the dampener.

Steve: I went to the Summit website and checked on the CP7529 digital timing light as well as various MSD ignition systems. The three MSD ignitions I checked all indicated they are multiple spark discharge, and the CP7529 timing light specifications indicate that it WILL NOT work with multiple spark discharge. Since I do not know the specifics of your MSD ignition system, it appears that this is not the timing light you want. The standard Actron 7519 dial-back timing light indicates that it IS compatible with multiple spark discharge. But then you need a separate tach.

Larry,

Thanks for the reply but I may have other problems. The balancer may have slipped. I can't seem to get this thing in time. My other problem may be that I did not get the cam in sequence with the crank. The car has run for over 10 years but it always lacked power and balked when I stepped on it. So it could be a two fold problem. I figured with a dial back I could start the timing out at the 12 to 14 Degrees advance and then check to see what the total is without the vacuum. May just run it that way.

Steve
