Vacuum/Carb

I have no vacuum lines going into carb, both are plugged. Also the port on the dizzy is plugged. Been quite some time since ive messed with carbs....
From what I remember the port on dizzy is for vacuum advance?

Plugged ports


High Idle , around 1100 rpms (right port on carb)


Reg idle 700ish rpm (right port on carb)


High idle (left port on carb)


Reg idle (left port on carb)
Forgot picture but the vacuum was non existent.


I found carb manual, the left port is "ported vacuum port"
The right side is "full time vacuum port"

Im guessing the 'ported port' would be for vacuum advance as it creates more vacuum with higher rpm.



Edit: I checked timing couple weeks ago, cant see markings but it is either advanced or retarded a bit (im guessing advanced....)

She'll stumble on take off once in awhile, just chokes out for a sec, makes a fart out the carb, then gets back at er.
Trying to get this thing running optimal.
Apprecaite any/all feedback. Thanks!
