OK now, to be sure, I can check all 4 at the same time, or check all 4, one at a time, engine at idle?
You are welcome, It's really easy to check, the little cap(s) have a small flat blade screw holding them down. With the engine OFF, crack the screw loose, hold the cap down with a finger, the metering rod/spring will be pushing up on it. Then loosen the screw and rotate the cap just enough so you can see the metering rod, then tighten the screw to hold it down.Push the the metering rod down and let it spring back up, it should psuh down with little pressure and spring right back up. Do this for all 4 metering rods, that way you know none of them are bound up and the springs are't broken or bad. This should take a few minutes to do. Then hook up a vacuum gauge and start it up. Watch the metering rod assemblies, they should be bottomed out. You can push down gently with a screwdriver to verify that they are bottomed out. Again if they are, you are golden. If they are bouncing around, look at the vacuum gauge to see what springs you are going to need. If you don't have it I'd recommend the Carter/Edelbrock carburetors book #SA130 It's got lot's of pictures that are easier to process than a wall of text. Have fun
