holley idle screws
hello i was wandering if any one could tell me if all the holley double pumper carbs have the 4 corner idle system my carb is a 750 dp the number on it is a 4779-2 it does not have the two back adjustment screws but there are spots for them but the holes are not threaded and i seen the newer carbs had 4 adjustment screws but this carb was bought around 1980 any help would be appreciated thanks

Most holley dp`s DONT have 4 corner idle. The race versions and the newer HP series do.
