Hello, im new to thirdgens and my camaro have a canadian 305 engine from 1983, with a 4 barrel Rochester quadrajet. I have deleted EGR and charcoal canister. The only things i will connect on carb vacuum ports are :
distributor advance (port H)
choke diaphragm (dont remember which port)
Brake booster (big hose)

I have seen many vacuum diagrams and dont know which port is for the choke. Also, initially, i runned the engine with distributor advance connected on port N instead of port H for the first 100 miles road test , do you think it could have caused driveability issues? It runned great when hot, but crappy when cold. Today, i will connect the distributor on H port and see if it go better.

Do you know which port is for the choke diaphragm?
