I think it's the stock carb. It's 2bbl for sure. I'm not sure if it's stock or not, but I am certain it is. I'm hesitant about even taking it out at this point. I have an uncle who rebuilt his own transmission, partially rebuilt the engine himself, whatever. He said that I need a timing light and tune the whole engine up before I even think about the carb. (I mean, I won't lie. It needs a new distributor cap now that I've looked at it, new spark plug wires, likely new plugs, and a new rotor).
What I still don't understand is why it started doing this immediately at one time. It happened right after I put new tires on it. Before, it ran perfectly fine. Sure, it ran rich, but it never got to the point of which it vibrates, makes weird knocking noises, rushing fluid sounds, etc. (I'm uploading a video of that right now to Youtube). It also started doing this carburetor garbage right after I put the new tires on it, which is weird to me. I was there the whole time when they put them on, so I know nothing went on when that was being done.
Here's another question. I took some wires off of my distributor cap and put them back on. No backfires, as I am certain I put them on correctly... but maybe I didn't and it's not behaving properly? But the problem started before that... so I somewhat doubt it.
I found a carburetor at "Rockauto" for $135. Sounds like it's a referb, but if it works it works. Apparently it's one of their best sellers. Oh, and it's 2bbl.
I would also like to verify this firing order
for a 1968 Chrysler Newport with a 383 in it. If I mess up the wires if I replace them, the rotor and the cap... I'd want to have a good resource to look at if I do mess it all up. So is this accurate on that page? (for those who know)
