total 49°@cruise with vacuum timing starting as soon as you move the throttle.This requires tuning as to get blades exactly in the correct spot for the vacuum pickup point with where the vac hole is located in base plate in this particular carby..i find a lot of them to be very different and the clone and quick fuels etc all different again.
This is his summer setup,winter will be different .This is in a heavy station wagon with 3.08 rear ratio.
