Geeze,
I'm getting ready to have the 250 rebuilt and was going to remove the dizzy. I took out the retaining bolt and hold down. The distributor will barely turn...I mean barely with all I can muster with two hands!! I can feel the gear from the hole where the fuel pump was removed and it seems like it is not locked up there. Is it common to have to pry them off after they have sat for awhile(1 year)?

Put a little penetrating oil on tonight and will try again tomorrow....
