So Dan, like I said most likely it was your distributor as per Ned's theory.
Did you have the plastic gear still in the car?
I guess you could put back all those other parts you had changed before the ditributor then.
The onl other thing Ned told me to do is, since there is a little margin on the ditributor, try to set it as much clockwise but alowwing the car to start.
This worked for me atleast.
