I believe it's the idle circuit since it's only kept running at low RPM with pedal pump which means it's starving for gas. When it switches from the Idle circuit to the main jets at 2200 rpm it runs fine. This eliminated any fuel delivery problems and really points toward the metering block. I'll post my final fix when complete.
