Valve Installation
NOTE: Tap the valve stem only along its axis so you do
not bend the stem.
• When installing valves in the cylinder head, coat valve
stems with oil before inserting into valve guides, and
make sure all valves move up and down smoothly.
• When valves and springs are in place, lightly tap the
end of each valve stem two or three times to ensure
proper seating of valve and valve keepers (use ham-
mer handle bottom).
