If you had the slide out, there's an even chance you put the spring plate back on it upside down. This is a common mistake made more common by the fact that it looks like it ought to go that way. Make sure you have it with the flat edge, the side with the hole in it, facing down, as shown here: (item #11, center of the page. It causes symptoms much like you describe, and it's because it's too rich at under a third throttle)
