I am attempting to change out the distributor/rotor adapter. It is a keyed shaft. I have removed the screw and was told to give it a quarter turn and it would slide out. The screw is out, but cannot get the quarter turn in any direction. I have tried to just pull it out and that is a no go. It is frozen in place. How or what do I need to do?
There is nobody in my area willing to work on it.
