what`s wrong with my holley??
I have a 600 vac. sec. holley list 1850-2. I rebuilt it last summer and never ran it till today. It won`t idle under 1500 and I have to have idle mix screws out 4 turns and the idle screw almost all the way down just to keep it running, I can`t get the floats any lower and gas still runs out the sight hole. at around 3000 it smooths out but it`s still RICH as hell, just this HUGE cloud of black smoke behind my Zed.

what's your fuel pressure at?
did you clean out the needle and seat really well? did you check for vacuum leaks...sounds like you have a few of them.

Did you happen to adjust the screw under the back passenger side that adjusts the secondary flaps when you did the rebuild? This will do it also.

when you rebuilt your carb and wiped out your fuel bowls you may have messed up your float settings, id check those if your still pouring gas out the feul level holes.
