distributer cap mods?

Johnny i dont take don's word as the gospel, he says edelbrock carburetors are junk and blames all my problems on it, but i'm still running my edelbrock carburetor. He also said i need to run 16 degrees initial timing 34 degrees total timing with 14 degrees of timing added to idle from vaccum advance for a total of 30 degrees of timing at idle, i dont do that. I run 15 degrees initial 33 degrees total and 10 degrees of timing added at idle for total of 25 degrees at idle.
The only reason i have stuck with running the vaccum advance off of manifold vaccum is because it truely does run better that way, if i could get it to run better off of ported vaccum i would run it off of ported vaccum....
