KINROAD 150 SERVICE MANUAL
Turn the cooling fan clockwise until the mark of the timing drive
sprocket on the camshaft is at top dead center, and the "T" symbol
(or other mark) of the magneto flywheel aligns with the crankcase
mark.
The crankshaft should co-rotate; otherwise the
exhaust port may not be adjusted.
When adjusting, loosen the lock nuts; adjust the bolts with a
valve-adjusting wrench; if turning clockwise, the valve clearance
decreases, and if turning counterclockwise, the valve clearance
increases. Then, put a feeler gauge with specific size between valve
and rocker to check for correct clearance.
Take out the feeler gauge; tighten the lock nuts, and then inspect the
valve clearance again.
Sometimes when tightening the lock nuts,
it will change the clearance. So it must be
rechecked for the proper clearance.
Valve clearance
CAMSHAFT
The camshaft is a main driving unit of the valve train. There are the air inlet cam, the exhaust cam, and the
cam journal on the shaft. It controls the intake and exhaust valve to open and close at the correct time. The
camshaft wear will affect engine performance and cause excessive noise
CAMSHAFT REMOVAL
Loosen valve cover bolts and remove cover.
Remove the cam chain tensioner screw, and remove the O-ring.
Tighten the cam chain tensioner-adjusting bolt clockwise.
