3. Remove the six screws attaching the valve cover(s).
4. Make sure the piston is at Top Dead Center (TDC)
of its compression stroke (both valves closed). To
get the piston at TDC, pull the recoil handle slowly
while watching the piston through the spark plug
hole. The piston should move up and down. The
piston is at TDC when it is up as high as it can go.
5. Insert a 0.006 in. (0.15 mm) feeler gauge, for intake
clearance, between the intake rocker arm and valve
stem. Insert a 0.008 in. (0.20 mm) feeler gauge, for
exhaust clearance, between the exhaust rocker arm
and valve stem. Correct clearance is when a slight
drag is felt when sliding the gauge back and forth. If
the clearance is either excessively loose or tight the
rocker arms will need adjusting.
To adjust valve clearance:
1. Hold the rocker arm pivot with a wrench and loosen
the pivot lock nut (Figure 4-7).
The rocker arm jam nut must be held in place as the
pivot ball stud is turned.
2. Loosen the rocker arm pivot and turn the rocker arm
pivot to obtain the specified valve clearance. The
desired clearance for intake and exhaust valves is
the same.
3. Hold the rocker pivot with a wrench and tighten the
lock nut to 69 ft./lbs. (7.8 Nm).
4. Install new valve cover gasket.
Start all six screws before tightening or it will not be
possible to get all the screws in place.
5. Re-attach the valve cover. Torque fasteners to 20-48
in./lbs. / 2.3-5.4 Nm. Torque fasteners in a cross pat-
tern.
