carb issues

I also found that if I shoot carb cleaner in the primary idle air bleed (inside the choke horn area) for the passenger side, it made the idle speed up a little. Shooting it in the driver's side one made the idle die down and stumble.

Okay, you are having the opposite problem as Brian is. He has a clogged idle air bleed, but you have a clog/restriction in the idle well, on the passenger side of the primary metering block. You want to remove the mixture screws, and spray Brakleen (green can) in the opening where the passenger side primary jet is. Compare it with the other side, and when they both spray out the same on the other side, you should be good.

I also noticed my idle is now up to about 1,000-1100 rpms. I tried to get it back down under that where it normally would be, but it just wants to die then.

Just to clarify, adjust the idle mixture and timing with a vacuum gauge, and then turn down the idle speed with the idle speed screw.
