The number on the tag of my carb Indicates it is a '68 model AVS, it has only one adjustment screw that both my expert MOPAR mechanic, and a good friend (who rebuilt it, and said I really needed new metering rods, but we can't get any for it) cannot get it to work properly. The car runs much better with it rebuild, a new distributor, tune up, but still rich, and sluggish. Much worse than when I bought the car 2 1/2 years ago. The place where the adjustment screws should be are factory plugged, and I have been told there is nothing to be done about it, the cost would be prohibitive. So now, I have accepted that I need to spend more money I don't have, and get a new carb. Which one, AFB, or AVS. I loved my AFB on both my '63 Custom, and '60 Crown Conv., both long sold now. Once again, it turns out that the engine in my '66 is a '74 HP 440, built in May of '72 (God knows why), a '67 manifold, and the whacky '68 AVS. Which carb would be best, what CFM for daily driving, that gives the most punch, and better than the 6 mpg I get now (8-10 on the open road, woo, woo!) Also, in the big picture, I want to rebuild this decompressed, low hp, post 1970 engine to at least the proper spec's of a '66 440 with the proper hp. I know that at some point they switched cranks, I don't know which would be in my engine, or which it should be when it is rebuilt. I hope this all makes sense, and any advise is truly appreciated. I guess I could try to buy a '66-'70 Chrysler with a 440 in it and verify it is the original engine, rebuild it and swap it into my Crown Convertible, than sell the Chrysler, but I hope I can rebuild mine to it's true pre '71 glory hp days!

It's factor set or something. I've never heard of this and I thought they only did that with the later emission control carbs. Mid 70s-early 80s. I would assume when they rebuilt it they could have restore the adjustability. That's why he wants a replacement. Rob >From: Elijah Scott <imperial1971@xxxxxxxxx> >--- "Wm. R.
