You will never get a clean idle with 14deg of timing with that cam.
Lock out the distributormechanical adv. Use a SPST spark power interupt switch to allow easy starter cranking when hot.
goes on the spark box power on switching wire.
Crank it over 1-2-3 with no spark and throw the switch , it will fire right up.
set the locked timing at 34-36deg BTDC. It does not move with rpm.
The big cam needs this much timing at idle.
Now you can close the carb throttles down .020-.030" exposure at idle and it will idle clean. Power valve should stay closed at idle when in gear.
A 3.5 or 4.5 usually gets that done with a big cam.
just do it. You will see.
I tried to find that cam based on your specs. What cam is it ?
if you want to run 24ish idle timing with a mechanical timing curve limit the mechanical curve travel stop to 10deg.
24 +10 = 34deg at max advance.
Try the simple locked out timing, first.
