I have come across a 4V square bowl Holley that I took off a running
FE. It performs perfectly. Electric choke no secondary metering block
style, problem is there are no idle screws. How are you suppose to
adjust the idle. I cannot find any listing on this one. Been to the Holley
site, I have many Holley books with all the List Nos. No Luck. I want to
put it on my 53 F900 instead of rebuilding because I can't lay up the
truck waiting for carb kits. So anyone know what model this is??

Could it be one of the "emissions" carburetors from the mid 70s? I have seen some of those with fixed idle circuits. Sometimes an earlier metering block can be used to get the idle screws.
