Idle Transfer Slot on secondaries?

Carbs are a case of suck it and see. :lol:

It may easier to just get an after market main body with adjustable air bleeds to play around with. The pain in the arse with Holleys is changing IFRs at least with adjustable IABs you get a better understanding of what your engine wants.

If you open the throttle valve too much it will make the idle screws unresponsive.

Well sitting on my bench is this…… I however would like to try and get the Holley 650 working as a challenge and learning tool. But those adjustable air bleeds are definitely looking at me straight up!
