@papasmurf1 valve clearance with valve springs installed and piston 1/4in (6mm) past top dead center (check when engine is cold):
Intake.............0.003-0.005 in. (0.08 - 0.13 mm)
Exhaust..........0.005-0.007 in. (0.13 - 0.18 mm)
Valve Clearance Adjustments
+
Adjust Valve Clearance
+
Valve clearances should always be adjusted on a cold engine.
+
1. Remove the valve cover.
+
2. Rotate the crankshaft in the normal direction until you get to TDC (Top Dead Center) of the compression stroke.
+
3. Insert a narrow indicator (screwdriver or small rod) into the spark plug hole against the piston to indicate piston movement.
+
4. While watching the indicator, rotate crankshaft clockwise (CW) past TDC until piston is 0.25 in. (6mm) down from TDC.
+
This is to prevent the compression release (if equipped) from affecting adjustments.
+
5. Loosen the jamb nut on the rocker arm.
-
6. Insert the proper feeler gauge. While moving it back and forth, carefully tighten
-
the adjustment screw until a slight amount of resistance is felt on the feeler gauge
