Again, I’m no expert. I would put the bigger IAB’s in and see what the changes are. Anything over 1/2 turn on the idle mixture screws (up to 1 1/2) is acceptable as I understand it. I’m curious as to what the guru’s here will say.
I tried as big as .090" and also tested with .060". The only difference I see is amount of turns on the screws. I am guessing my IFR is too small? I will remove T-slot restrictors completely, this should show dramatic change if they are too small.
