I pulled the Distributor and dissembled the unit as required to remove/ replace the "internal Pic-Up coil:. But i guess did not clean the shaft and now there is a lot of
Play, I can pull the rotor /shaft up and inch.
The Engine Idle fine but i guess the shafter moved up under acceleration and damaged my Rotor, I have the Shaft and Housing soaking to loosen it up.
Does any know if there is a mark where the two should meet? or how much play there should be?

The pin that holds the gear on prevents the shaft from moving vertically. .020 about
 
I have never heard of that kind of play
 
Did you put the gear on in the right orientation (upside down? rightside up?). Miss a spacer or two?

There should be very little play, or the spark timing is going to be all over the place.
