[QUOTE="Gilaguy23, post: 436468, member: 19498"] Id say that's not the original carb as I see a part number sticker still after 30 years?, as well as capped vac lines. Not necessarily a bad thing and that's how you get a rebuilt sometimes with a few unknown nipples on it, but these carbs are not known to be exactly problem free or good running. The line with a bolt in it by the PCV valve might be a tank vent line that should be corrected ,but Its hard to tell without tracking things back to where they go. In the vid its hard to tell what the noise is other than a rattle of some sort. I was expecting to hear a rod knock or lifter tick but its surely not the case. Your gonna need a timing light to time it correctly or have a shop do it. Id be checking for vacuum leaks around the carb, make sure the carb upper and lower halves screws are tight as well as the base bolts. Check the manifold gasket for intake leaks, and that the brake booster diaphragm isn't shot. Its s a start anyhow. If it were mine Id install a Howell FI kit and shitcan all those vacuum lines and smog line spaghetti. [/QUOTE]
