Edlebrock 1405 carb surge

Another compromise fix, which I do often, with street engines, is to use a steel plate to block the exh xover. I drill a 1/2" hole in the plate so that the intake gets some heat. Liquid petrol does not burn, it needs to be in vapour form & heat coverts it to vapour.
Good point. Thanks.
Have you rotated the adjustment housing?

-the black part of the housing next to where the 12v wire attaches.
