  1. Which system is it? hydrovac (line activated) or pushrod activated.
  2. I don't think it's your carburetor. Old Buicks could run the vacuum tank dry on long pulls with lots of throttle just because they weren't making enough manifold vacuum. I think you already have the fix with your assist pump.
  3. To answer one question: removing the axles is quite easy. you have to remove the pin that goes through the differential gears. There is a cross bolt that holds the pin. Once the pin and spacer are out you can push the axles in and remove the clip, then pull them out. If you turn things the diff gears may fall out so you might want to stick something in the hole to keep things in place. Adjustment isn't really an issue. There is a spec, I think .008 but not critical. If less that .025 I wouldn't be concerned. There used to be oversized blocks but good luck finding that. Re the seal: I ne
  4. Hint on the turn signals: if you have dim bulbs it's the BULB ground. Either the dim one or it's buddy on the other side. it's grounding back through the filaments to another bulb.
  5. If your car shakes at 40 it either has a wheel WAY off balance, which should show up with the above good advice. More likely (imho) is that something is out of round. A tire, rim not mounted properly, or even a wheel ( hope not). I would bet on a rim not sitting correctly.
  6. It looks to me like that link hanging down in front of the starter is the one for the gas pedal.
  7. If it's like most pinions just tighten it until there is no motion sideways or fore-aft in the pinion shaft, then apply a LITTLE more to give it a bit of preload. it should turn freely in the bit of backlash that you can feel, with a slight bit of drag from the preload. When you can't decide if it's too loose or too tight- - it is right.
  8. To balance the carbs you need a vacuum gage. There appears to be a port on the side to connect the gage, then balance for idle speed, then adjust idle mixture for best vacuum, then back to speed setting. Go around the circle a few times and it should work.
  9. Not the first or last. I've had guys bring me vehicles with serpentine belts that were knocking and they were sure it was dying. Chunk out of the belt!
  10. Bounce: I cant seem to reply to your email. I pm'd you
  11. Sorry about your stuck clutch Can you hold the pedal down and pry on the metal lugs along the pins to separate them?
  12. I dug up original picture. There is so much reflection in the windshield I can't tell if right or left drive. There is a W in the center of the headlight bar where it would say Zeppelin. A monogram? Horns certainly look like the ones on the Nethercutt car. 1940 New York plate 4V36.60 Chrome edging around front fenders like the green car. Solid disc wheel covers. Trying to decide what the round emblem in the center of the bumper might be. Service club??
  13. Most cars are clockwise. Like the man said. Every repair shop has a box of bits that will have what you need.
  14. Chrysler products generally used positive ground until alternators came along. It doesn't matter a lot. There are regulators for Pos and regulators for negative but a PA won't have a regulator - at least not originally. Why is another question. Generally electrical circuits use positive logic. That is, things run from positive through the circuit and back to the negative terminal. Sometime in the history of the world they discovered that electrons are what is doing the work. These are negative particles, so some engineers decided that if the flow was electrons it must be from negative
