I find this interesting . Bought a Cardone dizzy for points and was happy the cam lobes were much better than the one I replaced. {2 lobes worn down} Was fine and last summer and this summer getting detonation. Part throttle and tip in on the throttle. WOT not so much so I rebuilt my Edelbrock carb as I have never been in it ,,floats were off but fine.
Still a rattle . Rebuilt the carb because there was no rattle before so I thought it was dirty.
Looks good fine,,checked off my list. Removed the vac advance and plugged ,better but still there. Went to my buddies garage to get a metering /jet kit I lent to him for his carb which is the same as mine. I wanted to richen the mix. He says lets check the timing to make sure. Ok ,,set it up base was at 12 ,,,fine and run it up it goes to 35 or so at 2500 rpms and any higher it bounces up to 44! Ok I pull the dizzy expecting to find a dropped /broken spring in the mechanical advance,,,,,nothing ,all good. Thought to look at my old dizzy that I replaced and the same but something was different.
The one on the left was my old one . The one on the right is the reman Cardone one.
I noticed the slots were very different. I sent a PM to HALIFAXHOPS the guru i feel on anything dizzy for our cars. He said the base plate Cardone installed was for 34 degrees on mechanical advance and rather rare. I asked him what could it be for and he said if I remember correctly ,,smog engines and trucks! He said that was most likely my problem. He also advised to try a FBO mechanical advance limiter. Looked it up and although I had heard of such a thing in the past I had no idea what it looked like or how it operated.
So here it is...

This is set at mechanical advance lockout but you can dial in how many degrees the advance can add. I have one on order and have read good reports from other mopar forums. Nice to be able to have 12 or more base timing and cap it at 34 or so. Sorry if old news . Thanks Halifaxhops!!!
