Valve Clearance Adjustment
Too large valve clearance will result in noise and
ultimately in damage of engine. Too small valve
clearance or no clearance will result in that valves are
not closed tightly, thus causing valve damage and
power loss of the engine.
Remove caps with big and small view hole,
respectively, from engine.
Turn crankshaft until the engine is at timing position
(Mark line “T” on rotor of magneto is aligned with
center of view hole.)
Remove upper cover of cylinder head
