Valve adjustment for OHV engines
(From: Mike's Small Engine (smallengineparts@yahoo.com).) You don't adjust OHV engines at TDC. You must bypass the compression release by turning passed TDC and letting the piston drop 1/4". Using a plastic ball point pen as a tool in your spark plug hole you can let the piston push the ball point pen out of the spark plug hole till it starts returning inside the cylinder. Make a mark on the pen so you can see the 1/4" drop of the pen. Then set your valves at 0.004 clearance for both IN/EX. Note: This is a general valve clearance specification that covers most engines today. Check your maintenance book or ask your local dealer for the info on the valve clearance for your specific engine.
