Super High Idle and Jerky Throttle - Rochester Monojet

[snowman4839]

Hey guys, I know I don't have a truck really but this place looked like it had some knowledgeable people about my problem. I have a 69 Buick Special Deluxe with a Chevy 250 in it and a Rochester Monojet MV. I just rebuilt it and put it on and now it runs fine but it idles insanely high. Like 1800rpm on the fast idle cam and 1500rpm after its warmed up. What on earth is wrong with this thing? I didn't have any extra pieces after I did the rebuild and I know I didn't lose any because I had them all in one bucket. I just put a new float, needle & seat, manifold gasket, and the gaskets between the air horn, throttle body and whatever the middle piece is called. What would cause this??

My other problem is that it doesn't want to function normally around the 2300rpm to 2700rpm range. It either runs below that or it stutters then almost dies and then jerks you into high rpms. What would cause that? (I still had this problem before I rebuilt it).

Thanks guys

EDIT: I know that this has nothing to do with the idle problem but I haven't replaced the points, cap, and condenser for the distributor.
