I have a pretty stupid question, but I want to avoid breaking anything. I recently got an '83 ZX Turbo, and it ran when I test drove it, then wouldn't start again. I checked it, and I plan on doing the GM HEI ignitor swap, but I also noticed one of the screws holding the distributor cap had it head twisted off. I want to get a pair of vice grips in and try to thread the old screw's remains out, but the rotor head is in the way.
Now comes the stupidity on my part- My FSM, which I got from Xenon S130, has no procedure to remove the rotor head. I noticed it has a mark that says 'screw' but where it points, is just the electrical contact. So, is there a screw under the contact? Does the rotor head screw onto the shaft? Or does it pull off like other rotor heads? I want to ask before I start yanking on things inside a 33 year old dizzy in the cold (brittle plastics are brittle.)
