I just added a BBK 52mm throttle body. It seems there is a "drag" just off idle when running. It takes some effort to overcome the initial throttle movement. Is the gap by the blades too small?

 

the blades could be geting caught when the throttle is let off. on the TB there should be an adjustment screw to keep it from doing this.

R1,

Follow the directions for setting the throttle plate minimum air position and you should solve the problem.
