Mr Xiggy.. temperairily lock out the timing curve. Set the locked fixed timing at 36deg BTDC.
Now reset the carb and . Now you can fine tune from there.
This may not be the idle spark advance you end up with but it is the place to start at.
locked out at 36deg BTDC is not too much. you can fool around with it from there.
26++++ deg base at idle for a cam like that. 36 fixed /locked is not too much for a cam like that.
The timing must not drop off when you idle in gear.
if you have a auto trans and this is the cam you got, you will find the locked out mechanical timing very effective.
Wether you use the carb you got or a holley or.... will not change this.
functional vacuum advance can be retained but will need to be set up. Use ported vacuum.
