?Jet performance carburetors

[az1970k5]

Anyone here have any expirience with their stage 2 quadrajets? They are sulposed to have all the modifications to correct the common quadrajet issues. I have one from National carburetors but not happy with the way it is running, bogs down and I have a hard time starting when hot or when it has sat for more than a couple days, also seems to flood wgen hot. It worked perfect the first couple weeks I had it. It is either this or an edelbrock.
