Need help with edelbrock 1406 carb

Dale, Post #53, comments, corrections.
The Edel AVS does have secondary boosters [ original Carter did not ]. An improvement in my opinion.
Well aware of the fact that large [ 800 cfm] carbs need bigger n/s for fuel flow, but the Edel 800 cfm carbs come with the same small 093 n/s as the 500 cfm model. They DO sell a 110 high flow version.
You misread my comments about air bleeds. I was NOT recommending or suggesting air bleed changes a la Holley. What I said was, Edel for some reason, [ I offered possible reasons ] chose a very low operating fuel level for their carbs, by using a 7/16" float setting. I have never seen a 7/16" setting for an original AFB/AVS, 5/16" being very common but have seen as high 3/16" [ Ford 430 ]. That is a 1/4" difference! Because the Carter/Edel carb body dimensions relative to the spill height is the same, Edel needed to change the A/F curve to suit the lower fuel level. That is done with air bleed [ by Edel, not carb owner ] & jet changes. Most Carter 600 AFBs came with 089 pri jets. Edel 600s come with 098 or 100 pri jets, a huge increase, which I suspect is due to the lower fuel level. The Edel met rods also had a bigger spread between the cruise & power steps.
