Secondary IFR/IAB
I have a 3310 with a secondary metering block. With no idle mixture screws and no transfer slot exposure is there any point in installing idle feed restrictions?
With or without IFR's where should the secondary IAB's be set? Presently they are at .070 - same as primary

Leave them at .070 as the secondary metering block JUST allows jet changes vs metering plate changes.
It also should not be drilled and tapped for a secondary power valve. The jets should be 6 sizes larger on the secondary side with the "Jet Change" metering block. No other changes required. Tom V.
