Holley stumble trouble

OLD Holley 650 DP. Non-adjustable air bleeds.
Stumble is in the transition from idle circuit to mains during very light throttle cruise. Like after coasting down a small hill and just starting to tickle the throttle at the bottom of the dip before rolling back in to it.


If that’s the case, you can open up the main air bleed .004-.006 and get it on the mains quicker.

Been awhile since I’ve been into one of those, so I have no idea what’s in them for MAB, IFR, IAB and such.
