Can you show me a picture of that?

Let me see if I have a Holley around the shop this weekend with this mod and I'll snap a couple of shots.  The only cars in the shop with carbs at the moment have Eddy's on them!

Very confusing that your base timing would be at 10° yet with advance all in it would be 45°

unless someone had done quite a bit of work to the advance mechanism...

 

Finally had a chance to do some more tuning work on my idle problem & vacuum problems. I stated earlier base timing set at 10* total advance at varied from 25* to 48* , I checked it again total was above 50* after going for a ride and heard some pinging. I looked around Oreillys has Cardone rebuilds for $29.00 put it in ran fine timing stayed steady at 12* base total advance was 32* at 3000 rpm's and it would run fine without vacuum advance connected. Started it the next day ran fine for 5 mins then died. Bought a new Proformance dizzy runs great comes with an ignition box that I can adjust everything with similar to an MSD 6AL.

The problem with my distributor was a worn Breaker Advance Plate and it had an 18L advance curve plate 36* plus 10* = 46 total advance, I have changed it to the 13L in the photo but I might just pull it apart and change everything over from the cardone for a spare.

 

This a pic of a spare 289 with 10L & 15L plates in it.

 

This is a pic  mine with 13L & 18L plates in it.

 

 

This is the worn out breaker curve plate the plastic is worn and loose causing it to stick locking the advance.

Wow...    Good Find!!!

I've seen something similar to that on a 318 Dodge Challenger years ago....
