7. Measure the exhaust valve clearance using a feeler gauge.
Exhaust Valve Clearance Specification:
0.16 ~ 0.24 mm (0.0063 ~ 0.0094 in)
If the clearance is less than or equal to 0.24 mm (0.0094 in),
the cam pulley decompressor is likely binding. Go to
Cam
Pulley Decompressor Inspection
below.
If the valve clearance is greater than 0.24 mm (0.0094 in), go
to
Exhaust Rocker Arm Pivot Free-Play Inspection
CAM PULLEY DECOMPRESSOR INSPECTION
Perform this procedure if the compression measures more than 80 psi and the valve clearance measurement is less
than or equal to 0.24 mm (0.0094 in).
1. Rotate the flywheel until the cam pulley decompressor weight slot faces out.
2. Carefully inspect the weight position and confirm that it is fully retracted. If it is not fully retracted, replace the
cam pulley (
).
3. If the weight is fully retracted, operate the decompressor by
very slowly moving it to the opposite end of the slot and
gently releasing. Repeat several times. If the weight fails to
completely return on its own at any time (by spring force),
replace the cam pulley (
