The idle circuit meters fuel at low speeds only. when you raise the rpm, the main curcuit takes over.
This new, reformulated gas gums up very quickly. it sounds to me that you have some clogged
idle circuits. I had the same problem on my '82. Since the carb is now 20 years old, it would be a good
idea to clean it up. Take it completely apart and soak it in some Berryman Chem-dip. It's about
$13 but well worth it.

thats what I did ^
I remember marking every little piece to make sure where they all went but when I took the jets out I just threw them in the bucket.
(I was 16 and didn't know that the primary and secondaries were different) So I put it all back together and it didn't run "just right" so I said **** it and took it down to a shop and they said "We can't figure out whats wrong with it, it's almost like the jets are mismatched" doh. So I drove it home and swaped jets then she purred like a kitten

Yup, I found gum in my secondary apply circuit. The one that applies vacuum to the
secondary diaphragm.
What I did was, make a diagram of the top of the carb where each air bleed is by number,
then disassembled, dumped out the rust and scale, put everything into the dip (minus the
electrical and rubber parts) for 1/2 hour then rinsed with water. Blow dry w/compressed
air. Then before assembly, I shoot carb cleaner through every port, hole, orifice, and air
bleed. BE CAREFUL!! Some of the holes will shoot back!!! PTUEY!
Then I reassemble. Check your float drop and rise against the manual with the gasket
installed.
Have Fun
BTW do carb #2 since it's already out and ready.
