I don't have much experience with Eddelbrock Carbs.
Right out of the box the idle mixture was very easy to adjust. It starts right up, hot and cold, and has a very stable idle. My MAIN complaint is the severe bog when opening the secondaries. It may be that a stock '68 383 doesn't breathe enough to get the secondary fuel moving on a #1407 and adding a very tight converter (1100 RPM Stall it seems) to the mix equals a BOG condition with no realistic fix.
I'm hoping that with an AVS (Adjustable Valve Secondaries) I may overcome the BOG issues to a tolerable state until a better converter can be installed.
P.S. i did install the Mancini Racing Mopar Performance Electronic Ignition upgrade that netted little change on the Bog issue.
