I have a 600cfm Holley and all of a sudden out of the blue my car will not idle. When i push the clutch in or sit in nuetrel she stalls. I have adjusted the idle up and it still does it. What could be causing this? The carb has only been on for like 2 months it shouldn't be doing this.

Is the choke operating correctly when fully warmed up?..even if it did when you first put the carb on..is it now?

The choke is working correctly. I've heard that holleys are moddy and change with the weather. They say that when it gets cold the floats need to adjusted. Is thise true? Or is it a wise tail?

Never heard of the float tales.Usually set them and leave them no matter the weather.Have you checked out all the ignition items..fuel filter..the basics first?I have had to rejet at times due to extreme weather condtions but never had the car stall out due to that.Holley/Demon's are moody to the weather..I have had both now.IMO the Demon holds a tune better year round up here in NY.

Its a brand new holley just 3 months old. But it was the floats i took the fuel level eyes out and gas came pouring out. So i tuned them to what the manual said then i reseat the idle mixture screws with a vacum gauge like the book said and that fixed the problem. Now my clutch is gone though!! Its always one thing after another.
