One (light) spring has constant tension, the other heavier spring has a loose 'loop' that doesn't engage for the first few degrees...so the small lighter spring has to do all the work of returning the weights to the static position. Replace the heavy spring with the loose loop with another lighter spring with constant tension, and the problem should go away.

I already checked all of that but the problem has not gone away.
1) I replaced the distributor three times, double checking the weights and the mechanicals to make sure it was OK.
2) I also deleted and added gaskets, including a 10mm spacer I had for the other engine.
3) I replaced the intake manifold just in case it was cracked.
The problem is still there no matter what I do. My next step is to install a 32/36 Ford/Webber/Holley I have in house to see what the reaction is. I will however be installing the carb backwards due to the manifold requirements.
If this does not cure the problem then it will be time to yank out the engine and use one of the other motors I have in stock.
Interesting how something so simple can be complicated at times.
