I'll call BS!

4 corner idle carbs will have an IAB in the .072-.076 range in most every case in all 4 corners.

2 corners will have around an .036 in secondary.

No wonder it runs rich...

Disconnect the fuel source to your fuel solenoid. Put an .072 IAB in the outer side air bleed in the secondary side.

Like a bad Ginsu knife commercial.. BUT wait, THERE'S MORE!!!

BS?? On what my friend said. He has 100% not touched them. And like I said he bought this carb new just over a year ago. He gave me the carb because his new motor required a 1050.
