vac advence is disconnect and base timing is about 20 if i remember correctly

so i got the car couple weeks ago. the pcv from carp was disconnected
so i put in back to carp. it idlesh okayeish but like every 30secs it shakes like crazy. it dosent stay running without gas on cold engine and manual choke dosent have like any effect.
i hooked vac meter to carp it only gets 7-10 vacuum, so i tried to adjust the idle mixture screws and it had very minimal change. if i let it idle like 15mins temps rise to 212f where i shut the car off, it dosent puke coolant. but im not sure if the temps is because mechanical fan is 2inch from rad and theres no fan shroud, i alredy checked to thermostat in boiling water and drilled 2mm hole in it. what i should check next :eek: thanks in advance :=)
Check your total timing/full advance.
20 initial would more than likely make it run cooler at idle and not hotter.
The fan ,it needs to be about 3/4 -1" from the radiator, not 2, or it will run hot till it gets moving through air 'at speed '.
Pcv hooked up making it cough here n there could be a blow by issue or maybe you are not readjusting the idle mix screws afterwards?
