Checking the compression pressure
1. Start the engine, warm it up for 5 min-
utes, and then turn it off.
2. Remove the lock plate from the engine
shut-off switch on the remote control box
or tiller handle.
3. Remove all spark plugs, and then install
the special service tools to each spark
plug hole.
CAUTION:
Before removing the spark plugs, remove
any dirt or dust that may fall into the cylin-
der.
4. Fully open the throttle manually, crank
the engine until the reading on the com-
pression gauge stabilizes, and then
check the compression pressure.
5. If the compression pressure is below
specification and the compression pres-
sure for each cylinder is unbalanced, add
a small amount of engine oil to the cylin-
der, and then check the pressure again.
NOTE:
• If the compression pressure increases,
check the piston and piston rings for wear.
Replace if necessary.
• If the compression pressure does not
increase, check the valve clearance, valve,
valve seat, cylinder sleeve, cylinder head
gasket, and cylinder head. Adjust or
replace if necessary.
Checking the oil pressure
1. Remove the cover.
2. Remove the oil pressure switch, and then
install an oil pressure gauge
1
to the oil
pressure switch installation hole.
NOTE:
Use a pressure gauge with an adapter that
has a 1/8 pitch thread.
3. Start the engine and warm it up for 5 min-
utes.
4. Check the oil pressure. Check the oil
pump, relief valve, oil filter, and oil
strainer if out of specification.
