If the flow does not slow down to a drip, check the governor
position. Also, make sure that the engine is before TDC on
the compression stroke.
Turn off the spill port pump.
Check the degree wheel on the vibration damper to see
what engine degree the timing pointer is indicating. This is
spill port static timing. Compare this number to the timing
specification for your particular application.
If the fuel injection pump static timing, as measured by the
above method, does not agree with the specifications you
have been given, remove the large nut that fastens the fuel
injection pump camshaft to the fuel pump drive gear. If the
crankshaft has rotated, turn on the spill port pump, and
rotate the crankshaft to find port closure.
Turn off the spill port pump.
