<VV> Corvairs carb tuning question

[Charles Lee]

My 67 Monza PG is finally running fairly well, but I have a question about 
the turn-screws at the base of the carbs -

What is the procedure for balancing carbs ?

My problem is that I turned them BOTH in 100% at the same time and the 
engine runs the same.
It does smell much less NIX-oious however ...

Ida thunk it would stall at that point, or at at least run worse with one 
turned in all the way ?

I have a "Keep your Corvair Alive" book here somewhere, but I can't put my 
finger on it right now ...

Am I doing this right ?

Thanks!
Charlie
