Idle Transfer Slot on secondaries?

That should be a good start. Change the base plate to the Holley and relocate the IFR to the lower part of the metering block so its submerged. Does the main body have a Tslot restrictor in the body?

Do this to both carbs regardless of which one you wish to use. This will calm down your idle circuit and make tuning exponentially easier.

My guess it doesn’t have have one, my Quickfuel didn’t, drilled and taped the body and made my own with brass set screws.
