2.
Run engine for 10-20 seconds.
3.
Shut engine off. Remove the vent line clamp. A
rush of air should be heard, indicating the oil pump
is properly primed and ready for field operation.
Note: If the system is primed properly you should
hear some air release. If you do not, the system
has not primed. Repeat the process if necessary.
VALVE CLEARANCE
Inspect and adjust valve clearance while the engine
is cold and the piston positioned at Top Dead Center
(TDC) on compression stroke.
1.
Remove the seat.
2.
Remove body panels and fuel tank as necessary
to gain access to valve cover.
3.
Remove the spark plug high tension lead and
remove the spark plug. CAUTION: Place a clean
shop towel into the spark plug cavity to prevent
dirt from entering.
4.
Remove rocker cover bolts, cover and gasket.
NOTE: It may be necessary to tap cover lightly
with a soft-faced hammer to loosen it from the
cylinder head.
5.
Remove timing inspection plug from recoil
housing.
CAUTION: Failure to position the crankshaft at TDC
on compression stroke will result in improper valve
adjustment.
6.
Rotate engine slowly with recoil rope, watching
the intake valve(s) open and close.
NOTE: At this point watch the camshaft sprocket
locating pin and slowly rotate engine until locating pin
is facing upward, directly in line with the crankshaft to
camshaft center line as shown. The camshaft lobes
should be pointing downward.

7.
Verify accurate TDC positioning by observing the
“T” mark aligned with the pointer in the timing
inspection hole. In this position there should be
clearance on all valves.
INTAKE VALVE CLEARANCE
ADJUSTMENT
1.
Insert a .006
″
(.15mm) feeler gauge between end
of intake valve stem and clearance adjuster
screw. Note: Do not stack more than one feeler
gauge to make .006
″
.
2.
Using a 10 mm wrench and a screwdriver, loosen
adjuster lock nut and turn adjusting screw until
there is a slight drag on the feeler gauge.
