Timing belt change-do I have to reset the timing?

What is your question?

I have a 05 civic dx 1.7 I took the the old timing belt off and put the new one on and replaced crank seal.. I put crank bolt on and used my ratchet to manually turn the motor to check the belt was on correctly and everything moves bout 6 inches then feels like something is stopping the movement so I then turned it clockwise and it got back to the original position and went bout 6 inches and stopped. What could b the problem be? I did not set the time before I did any of this and there was nothing wrong it besides oil leak from the crank seal.
