8. Observe the vial reading and refer to Fig. 19 to determine whether the injector fuel output falls within the
specified limits. If the quantity of fuel in the vial does not fall within the specified limits, refer to
Troubleshooting Chart 6 and Shop Notes in Specifications and Troubleshooting for the cause and remedy.
Refer to Specifications and Troubleshooting for different factors that may affect the injector
calibrator output reading.
The calibrator may be used to check and select a set of injectors which will inject the same amount of fuel in
each cylinder at a given throttle setting, resulting in a smooth-running, well-balanced engine.
