Hyundai Repair: Hyundai Accent, clutch master cylinder, hyundai accent

Question
I recently replced the clutch (Kit form). Th car was driving Ok, but the Clutch pedal was very smooth. The gears go in OK, and i can sometimes drive OK. Most times the car will race, when the accelerator is put down. I cannot go from 1,2,3 etc and when i drive down teh gears, there is no slow down. The bleeding and all is Ok but there is no power to teh Car.
Other times it runs OK, and as good as new.?

What can this problem be. Also it happens when i have driven for a while. Early morning is fine.  

Answer
It sounds like the clutch is slipping.  Make sure your pedal has the proper amount of free play, especially if you made an adjustment to this during your repairs.  I'm guessing there is too little free play, and when the car warms up, the clutch master cylinder sticks partially engaged.
