merely bleed down rather stop quickly Such situation could cause few agonizing moments pilot middle match since couldnt leave pilots circle because engine still runningalthough very low power level Removing large filter produced quick en gine stops instead bleed-down moral story keep small quantity fuel inboard needle valve spray bar possible admonition includes size placement fuel filter points
