12's with TBI and a "normal" carb engine  . Told you it wasn't the TBI nore air flow that was the problem... it's all about having only 2 injectors and fuel starvation. From just seeing these small GN motors idle at less than 1000rpm with 60lb injectors I've come to the conclusion that you should always overshoot on injector size!
