That is next on the To Do list, pull the plugs and look under the cap. ;D

So the more I dig into this neglected truck the more I'm finding. The owner has been driving it 'As Is' because his car has been in the body shop for a while (Hail Damage). Finally got it for a few days and found the plugs hadn't been changed for a long time (gap ~.060) a couple plugs wires failing and the centrifugal advance wasn't doing anything, totally stuck. Was able to free it up without removing the dizzy. New plugs, wires, cap and rotor and it runs so much better now.
Next time I get it, I'll be doing the carb. Rebuild kit (from Cliff's, of course) and primary throttle shaft bushings. Bought a Ultrasonic cleaner and picked up some highly rated (aren't they all ;P) Amazon cleaner. It works pretty good, as good if not better than the Berryman stuff.
