164-3310     Infrared Thermometer     1    When the engine runs at low idle, the temperature of an exhaust manifold port can indicate the condition of the components that transport fuel to that cylinder.A low temperature indicates that no fuel is flowing to the cylinder. An inoperative fuel injection pump could cause this low temperature.A very high temperature can indicate that too much fuel is flowing to the cylinder. A malfunctioning fuel injection nozzle could cause this very high temperature. Use the 164-3310 Infrared Thermometer to check this exhaust temperature. The Operator's Manual, NEHS0630 contains the complete operating and maintenance instructions for the 164-3310 Infrared Thermometer.
