Have you tried this:
Run it at 2500 rpm. Close the choke plate (or block what you believe to be
the offending venturi(s)) with your hand. Does it get better? If you have
a fuel starvation issue and you block a bunch of air, it should smooth out
as the mixture improves.
I'm not sure what the fuel is supposed to look like at that rpm as I'm
somewhat timid about sticking my face over a poor running carb at much
more than idle. I like my eyebrows intact.

Hi again experts,
I'm having a running problem that I still think is carburetion. It only
idles ok, and runs erratically at say 2500 rpm.
This is what I've done so far:
Changed distributor, cap,rotor, wires and plugs. Also have tested it with
another coil-same results. I've checked voltage to the coil too.
I've checked the compression cold and get 125 per cylinder across the
board. The engine has about 30 k on it.
I've also sprayed/checked for vacuum leaks, it seems solid.
I have personally rebuilt the carb with a kit and have had the top off
once to check to if the float level was ok..etc.
What I'm suspicious of the way the fuel looks going down the primary at a
steady 2500 rpm. It sort of drools unevenly in both venturis. The
"sucking" sound it makes is not uniform. I thought instead of slurping
or drooling in, it should look more like a vapor going in.
When I shut it off and look down the carb it stays dry like the float
level isn't too high.
I rebuilt the carb first because it ran this way before I did all this
stuff. This still "feels" like a fuel problem. If I had a spare good
carb, that would certainly prove it.
Any thoughts?
Thx,
Chris
