Not a typical hot rod engine. I have a chevelle with an i6 250. Bolt on upgrades only. 2 barrel holley,offenhauser intake,hei ignition and dual exhaust. I've had tons of trouble getting the idle right, and keeping it running. Typically I would look at a vacuum leak. But it idles very high when I start it and slowly drops until it dies. I can't bring the idle down with any adjustments that don't make it stall. I can blip throttle and it will stay running indefinitely. it doesn't backfire like a vacuum leak. I had the thought to pull the line to vacuum advance the idle instantly dropped,much closer to wear it should be,it idled much better. But eventually did again die. If I advance the distributor it has too much advance to start. The engine kicks back.
Does my distributor need heavier springs?
Maybe its choke related? I'm pretty confused.
