Reassembly
Testing the Engine
It is recommended that the engine be operated on a
test stand or bench prior to installation in the piece of
equipment.
1. Set the engine up on a test stand. Start engine,
inspect for leaks and check to make certain that
oil pressure (20 psi or more) is present. Run the
engine at idle for 2-3 minutes, then 5-6 minutes
more between idle and midrange.
2. Adjust the idle speed screw located on the
thrott le body as necessary. The standard idle
speed sett ing for EFI engines is 1500 RPM, but
certain applications might require a diff erent
sett ing.
3. Adjust the high-speed stop as necessary located
on the control panel (if so equipped). Make sure
the maximum engine speed does not exceed 4200
RPM (no load).
