amount of fuel may be present due to a previous chat­
tering test - this would be normal. If the fuel accumulates
and drips down during the test (about ten seconds) the
nozzle assembly is defective and must be replaced.
Spray Test
For proper combustion, the nozzle must effectively at­
omize the injected fuel.
1. Operate the pump handle at a rate of 20 - 30 strokes
per minute.
2. Observe the injector nozzle spray. The spray pattern
should be finely atomized in a broad, straight stream
(Fig. 19).
3. If the nozzle fails to spray properly, it must be cleaned,
repaired or replaced. (See Nozzle Service in the Fuel
System Repairs section of this chapter.)
