I just got a car from someone that never ran it and knows nothing about it. The car barely moves when I push on the clutch pedal. The pedal has no resistance while pushing on it. I bled the master cyl. and bled at the trans, and the fluid came out like it had pressure. while car was on jack stands everything seemed fine, but when on the ground with the weight of the car it barely rolls forward and back. Is it the clutches inside or the master cyl. or something else. I have never had any problems before with my Berts or Brinn to have to solve. Any opinions are appreciated.
