I think the "screening services" document outlines the carbs to look for with the relative interchangeability.
Although they keep creeping the price up on it, the Balvenie 12-year DoubleWood is still a great value in a single-malt Scotch at roughly $50. Smooth and drinkable without heavy peat.

Finally have a recently and cheaply acquired, gently used and freshly "rebuilt by Lars" '73 4MV installed, no leaks, idles great (had to slow it down so I probably need to check my timing) at 700 or so with a little lump, and jumps happily when I yank the throttle lever.
If the rain would just stop so I could road test.....it's killing me.

Ha.. good one! Not to change the subject but, you seem very knowledgeable when it comes to automobiles. I know this is not the right place to have this discussion so maybe I can PM you ? I have a problem concerning OBDII controls on a Dodge charger with a 5.7 Hemi. Maybe you can point me in the right direction? Been troubleshooting this thing on and off for year now. Let me know. Thanks

Not that I didn't believe you, Lars, but as you know I did this in reverse order.
But with respect to your comment...."You have a fuel supply problem not related to the carb. Throw that thing away and get a rebuildable carb. Fix your fuel supply problem first."
I've got a better handle on root cause but no great solution.
I made several passes through the gears with clothespins on the lines (a couple right before the pump and 5 after) and it ran nearly flawlessly, although it did starve out a little around 5000 rpm in 3rd.
Next question....what's the best fix for a vapor locking car that lacks a return line and on which I'm trying to maintain originality? Orange clothes pins?
