If you let them sit they wanna act stupid until you put a good day of driving on it to recondition the seals. At least mine acts fine after it sits and I drive it. What carb is it? I'm just running the 750 cfm that Discount sells. Hell of a lot better than the old Quadrajet that was on there. HAHA
demons are the shiznit! Before i got into sport compacts I was gonna get one of the demons with the adjustable venturi? sleeves so I could make a badass gass guzzlin motor for the truck.

They were too expensive for a 16 year old budget though. haha It was just a cool idea you could go from a 600cfm carb to a 1000 cfm carb in minutes. Of course then retune it.
