Yes
Charge the battery for 24 hours using
PN 06320-VH7-UA2 charger.
Go to “Hard Starting Using Recoil
Starter Or Poor Engine Performance”
on page 2-7.
Less than 12.7 V
12.7 V or more
No
Will the engine start using the recoil?
Check the no load voltage at the battery.
Contaminated with
grease or oil
Go to “CLEANING AND INSPECTING
THE PINION DAMPER ASSEMBLY”
on page 9-14.
Remove the starter motor and check if
the pinion is contaminated with grease
or oil (P. 9-12, P. 9-14).
Check the cranking voltage at the red
magnetic switch terminal.
Above 9.0V : Check the magnetic
switch for internal resistance.
Below 9.0V : Replace the battery.
If pinion engages
flywheel: less than 9.0 V
Check the cranking voltage at the starter
motor (P. 11 - 28
). Be sure the two starter
motor wires are installed on the correct
terminals before testing.
Pinion OK
9.0 V or more
(starter engaged)
Replace the starter motor (P. 9 - 12).
Compression
above 80 psi
Check the valve clearance (P. 3 -1 5). If
valve clearance is within spec, the
camshaft decompressor may be
sticking. Replace the camshaft
(P. 10-8).
Check engine compression (P. 1 0- 2 1).
Spec: 73 psi @ 600 rpm
OK
Confirm the starter wires are not
reversed. The white wire must connect
on the side of the starter motor near
the oil filler extension and the black
wire should connect near the muffler.
Check the cranking voltage at the
starter (starter spins but doesn’t
engage):
Less than 10.5V : Replace the battery
Above 10.5V : Remove the starter and
check if the pinion is stuck. Go to
“CLEANING AND INSPECTING THE
PINION DAMPER ASSEMBLY”
on page 9-14
.
Pinion does not raise
Briefly crank the engine and confirm if
the pinion raises and engages the
flywheel.
