The wrong throw out bearing in a kit would wave a large red flag at me. You may have the wrong clutch altogether. Whoever put the kit together likely knew which bearing went with which clutch but of course that is not guaranteed.

Hopefully you still have the old clutch to compare closely to be sure it is identical in every way. The fingers should be the same height from the flywheel surface to end of the fingers where the throw out bearing contacts them if the same bearing is used with both.

The 3 lever style with coil springs uses different throw out compared to the single diaphragm spring type. There are 3 different throw out lengths to my knowledge and they need to match the clutch that gets installed.

You don't mention which bearing was longer but if the old bearing that you installed is longer than the new one that came with the kit, it could bind at the back of the transmission bearing retainer and never let the clutch engage all the way, no mater how the pedal is adjusted. It could behave as if you had your foot pushing on the pedal all the time.
