Abstract
A hybrid fuel metering system has a first circuit (46, 62, 70, 76) to position a valve (18) to direct fuel to a metering valve (20), a second circuit (64, 76) to position the valve (18) to correct engine overspeed and a third circuit (78, 82, 70, 76) to position the valve (18) so that the valve (18) may be manipulated to meter fuel to the engine.
