just bought 85. 4-barrel on GM intake. Hard start. No idle cold. Starts w/accelerator pump. Won't move until warm. Electric fuel pump bolted to alternator. No vacumn to air cleaner or venting to charcoal cannister. evidence of two sending units in the intake, but no connections. runs good warm. Harsh upshift to second, but good downshift to second

How do I determine year and model of intake and carb. How to make carb/choke work? Vacumn in lower front of carb plugged. Large brass plated hose receptacle in front of carb open. Slight rough idle. Plugs? First elky...true love.
