Clutch Pedal Weak Return Integra 94 LS

Hey,
Just bought a 94 LS. Love the car. The guy I bought it from told me that the clutch was replaced 6 weeks ago. It shifts in all gears great and catches strong. My problem is the pressure of the return on the cluthch pedal. It will come up 3 inches strong then hit a lull with with almost not upward force then towards the top it is strong again. The problem is that weak area is where it grabs so it is extremely hard to perform a smooth shift. I have had lots of other 5spds and never felt a pedal like this. Is this normal to integras if not anyone know how to fix it?
Thanks

The guy probably did not bleed the system there is a steam value near the front of the trans and you will have to bleed the air out of the system. takes two people on to pump the clutch pedel and the other to control the value. Oh make sure you have some DOT 3 brake fluid (clutch fluid)
