Hey Paul,
What kind of show and when in houston? Not sure the car is road worthy enough yet.
I have found the problem..The wire lug that connects to the points and goes to the condenser was digging into the cap and not allowing the vacumm adv. to move properly. I have had that cap off many times and even replaced the advance bushings ... but some how managed to return it to the right position to bind up everytime.
Thanks, Clyde
