Thanks for the feed back Re-run.
The exhaust is a 4 into 2 into 1.  Not a 4 into 2 system.

I actually did start with the mixture screws out 1.5 turns.

Would not idle and would bog and quit when trying to rev the engine.
1 turn out did not help. (Of course it would be too lean then)

Putting in the #42 jets completely solved the problem.

I agree with what you say Re-run but the #35mm idle jets are so small
I like the #42mms because they will not clog up as easily.
