Prepare the Engine for Operation
The engine is now completely reassembled. Before
starting or operating the engine, be sure to do the
following:
1. Make sure all hardware is tightened securely.
2. Make sure the oil drain plugs, Oil Sentry
™
pressure switch (if so equipped), and a new oil
filter are installed.
3. Fill the crankcase with the correct amount, weight,
and type of oil. Refer to oil recommendations and
procedures in the ‘‘Safety and General
Information’’ and ‘‘Lubrication System’’ sections.
4. Adjust the carburetor, idle fuel needle, or idle
speed adjusting screw as necessary. Refer to the
‘‘Fuel System and Governor’’ section.

5. Before starting the engine, turn the engine over
slowly by hand. If it can be turned over completely
and compression is noted, the engine can be test
run. If, however, it cannot be turned over
completely (locks up at some point), return the
piston to TDC between the intake and exhaust
strokes and wait ten minutes to allow the lifters
time to bleed down, then check for compression
again. If still improper, repeat the hydraulic valve
lifter and rocker arm/pivot assembly installation,
for the head configuration used.
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. Install an oil
pressure gauge. Refer to ‘‘Lubrication System’’
section, Figure 6-9. Start the engine and allow it to
idle for 90 seconds. Check to be certain that oil
pressure (40 psi or more) is present. Run the
engine for 5-10 minutes between idle and mid-
range. Adjust the carburetor settings as
necessary.
2. Make sure the maximum engine speed does not
exceed 3750 RPM. Adjust the throttle and choke
controls and the high speed stop as necessary.
Refer to the ‘‘Fuel System and Governor’’ section.
