528 Hemi help

Idle Feed Restrictor....two in each metering block, another orifice to meter the idle fuel. Most billet metering blocks have these screwed in, so they are replaceable.

My Carb is running too rich at idle, did the same when putting in gear. After completely removing the IAB´s it´s running good, that tells me that the IFR´s are too big for my engine....and of course the A/F gauge.....it´s very useful for tuning.
