What to do if fuel leaks from metering unit?

Diagnosing the metering unit performance twice would be enough. Use different ladings and be sure to keep the pressure disk completely lifted for about 30 seconds.
What should I do if my Governor shaft is worn out?
If necessary, free up and align all linkages to remove any binding, and lubricate all friction points. Also, check to make sure there isn’t too much play in the governor shaft. Too much wear in the shaft bearing can change the centrifugal force action of the governor. This causes it to compensate too slowly when fast response is required.
