No....I just checked mine, the main needle is 2 and 1/4 turns out. There must have
been something way out of whack for JDW's engine to need 6 turns plus to get the
high speed set. I would guess that it was either lack of fuel pressure, or a restricted
fuel line, or some garbage in the main needle.

No.....
That's the very point of JDW's post - there was nothing out of whack other than the low speed needle setting.
His engine could be changed from a bad behaving poor fuel drawing engine that needed 6 turns plus on its main needle to run OK on a vertical line to a really good performing consistent engine that needed 3 odd turns of main needle at will, just by adjusting the low speed needle. I'd have not believed it had I not been standing next to the thing when he was doing it!
