I have a fresh 302 with headers, cam, intake.
I bought a holley 650 Dbl Pmpr, manual choke, mechanical secondaries new from Summit racing.
I installed the carb and want to know the correct way to make adjustments to get the car to idle correctly. I don't want to just start making adjustments and screw up the factory settings.
What its doing:
Not idling when cold, it stalls (it has a larger cam, not sure specs, came with car). i have to hit the gas to keep it from stalling every 10 seconds or so, when warm, the car idles fine.
when driving, and I come to a stop it stalls (usually) due to low rpms or feels like it is going to stall so I tap the gas to increase the RPM's.
when driving normal, there appears to be a little hesitation off idle when I floor it (not sure if carb related, might be ignition/timing issue).
So I know there is a screw that is attached to the linkage and will partially open the butterflies on the carb and move the linkage attached to the accelerator pedal a little and this will increase the idle rpms, but I'm not sure this is the "correct" way to do it. maybe it is? I don't know.
Like I previously said, I'm new to car engines, but not new to engines (small engines are no brainers, as are the carbs). get over 2 cylinders and I'm treading in unfamiliar territory.
