I can't dispute your findings, but the contention to me is, does using EFI and losing the carbs make the "balance tube" superfluous?
As much as i want to cut it out, I'm likely to leave it initially, then bypass it ,and then make a determination, more work, but a lot less risky if i choose wrong.
Was hoping to find some sound reasoning first.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
