Edelbrock tuning issues
I am betting your 1405 carb is plugged up.
One clue is if you take the 2 idle enrichment screws in the front of carb and turn them in and out. If they do nothing as far as how the engine runs then you know the carb is plugged.
Baseline setting on the 2 idle enrichment screws is 1 1/2 turns out from being bottomed out.
I use an Ultrasonic cleaner and distilled water and a little Pine Sol to clean them out good. Don't leave them in too long or they will turn gray. Heat up the cleaning solution.
Do it outside, so your garage doesn't end up smelling like Pine Sol.
Rinse with distilled water and make sure all the jet passages blow clean with compressed air. Lots of little runs in there that can plug off with gunk over time.
25 - 30 year old carbs here...
318 with 1406 4 bbl, runs great and plenty of power > enough to get into trouble.
