2. The oil drain plug, Oil Sentry™ pressure switch (if
so equipped), and a new oil filter are installed.
3. The crankcase is filled with the correct amount,
weight, and type of oil.
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. Start the engine and check to be
certain that oil pressure (5 psi or more) is
present.
2. Run the engine for 5-10 minutes between idle and
mid-range. Adjust the throttle and choke controls
and the high-speed setting as necessary. Make
sure the maximum engine speed does not exceed
3300 RPM. Adjust the carburetor idle fuel needle
and/or idle speed screw as necessary. Refer to
the ‘‘Fuel System and Governor’’ section.
