fuel regulated to >7psi.
Took off intake manifold/carb, resealed everything to assure no air leaks.
No progress.
Also adjusted the secondary butterflies so they are open a little more at idle, theory being that I can close the primaries more assuring idle circuit not transfer circuit is in use.
Used carb cleaner and compressed air in idle air bleeds, took idle screws out for the same treatment.

probably could have bought a new one for all the time/cash I've sunk into this. Might just do that yet.
