How many turns is the idle speed screw opened from the throttle just closed position live every 24 hour block of time like it's your last day on earth

What about the two mixture screws on the front of the carb? Make sure the transition slot is not exposed.

Especially in gear, have someone start the motor up after it is warmed up and then check the metering rods, if there not sucked down into the jets trim or replace those springs under the pistons on the metering rods so they do stay down in gear idling Mr.Cab Racing and winning with Mopars since 1964.

If so the metering rod springs are to stiff. It would be like a Holley with the power valve open at idle. Edelbrock makes springs that you can adapt. My race car idles with Edelbrocks with a 285@.050" cam with no issue. Doug
