the gasket. If the gasket is torn or damaged, it must be
replaced.
l Remove the spark plug so the engine can be rotated
more easily.
l Pull the recoil handle to rotate the engine to top dead
center (TDC). Looking through the spark plug hole; the
piston should be at the top (both valves are closed).
l Both rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine 360°.
l Insert a feeler gauge between the rocker arm and the
valve stem to measure valve clearance.
