For now, forget about the total timing. JUST for now.
Set the initial timing (with vacuum advance disconnected) to 14 degrees BTDC. Hook the vacuum advance back up to full time (aka "manifold" vacuum). Readjust the idle speed to around 800 rpm or so, or to where you like it. BTW, the vacuum advance can may be giving too much advance- you only need about 10-12 degrees from it, an adjustable can may be the ticket- but for now, run what you have.
Reset the idle mixture screws to give the highest idle speed, and readjust idle speed if needed.
Now, see how the idle and off idle response is. No need to worry about the total timing being too high- you're not going to be driving it yet. Don't run the engine under load until you have seen the total advance is 34-36 degrees or less w/the initial set to 14 degrees.
To get the right timing curve, the distributor may need modifying. But if the engine refuses to run right w/these settings, the cam may be out of phase.
You can check the cam phasing by using a dial indicator and a timing tape on the damper, but before doing that, see what you get by doing the above.
