MAINTENANCE
  Reinstall the bottom engine cover. Replace the screws 
and tighten securely.
  Replace the screw in the top engine cover and tighten 
 securely.
NOTE: Used lubricant should be disposed of at an  approved 
disposal site. See your local retailer for more information.
ADJUSTING CAMSHAFT-TO-ROCKER ARM 
 CLEARANCE
See Figures 13 - 15.
Inspect the camshaft-to-rocker arm clearance after every 
25  hours of operation. This should be done in a clean, dust-
free environment.
NOTE: This procedure requires partial disassembly of the 
engine. If you are unsure if you are qualified to perform this 
operation, take the unit to an authorized service center. 
  Stop the engine and disconnect the spark plug wire. Allow 
the engine to cool completely before proceeding.
  Remove the screw from the top engine cover. Remove 
engine cover and set aside.
  Using a Torx screwdriver, remove the screw from the 
rocker arm cover. Remove the cover and set aside.
  Position camshaft by pulling the recoil starter grip just 
until the deep hole in the camshaft gear is located at the 
6 o’clock position as shown in figure 14.
   Place the feeler gauge under each rocker arm and measure 
the gap. The gap should be between .006 in. (0.15 mm)  
and .008 in. (0.20 mm) for both rocker arms. 
 
NOTE: Use a standard automotive feeler gauge. The .006 
in. (0.15 mm) feeler gauge should slide between the rocker 
arm and valve stem with a slight amount of resistance 
but without binding. The 0.008 in. (0.20 mm) feeler gage 
should not slide between the rocker arms and the cam 
lobes — it should be held tight.
  If the valve clearance is not between .006 in. (0.15 mm) 
and .008 in. (0.20 mm), the clearance should be adjusted 
as follows:
 
  While holding a wrench on the flats of the adjusting 
  nut with one hand, loosen the retaining nut with a  
  second wrench as shown in figure 15. Take care not 
  to loosen the stud.
 
  Rotate the adjusting nut until it touches the feeler  
  gauge. Once the gap setting is correct, hold the  
 
wrench on the flats of the adjusting nut and retighten 
  the retaining nut securely.
  Adjust the second rocker arm, if necessary.
 Replace the rocker arm cover and screw; tighten 
 securely.
 Replace the top engine cover and screw; tighten 
 securely.
WARNING: 
Ensure all engine cover and all engine parts are com-
pletely and properly reassembled before starting engine.  
Failure to correctly reassemble engine may result in seri-
ous injury or property damage.
STORING THE PRODUCT
  Clean all foreign material from the product. Store idle unit 
indoors in a dry, well-ventilated area that is inaccessible 
to children. Keep away from corrosive agents such as 
garden chemicals and de-icing salts.
  Abide by all ISO and local regulations for the safe storage 
and handling of gasoline. 
When storing 1 month or longer:
  Drain all fuel from tank into a container approved for 
gasoline. Run engine until it stops.
HIGH ALTITUDE ENGINE OPERATION
Please have an authorized service center adjust this engine 
if it is to be run above 2000 feet. Failure to do so may result 
in poor engine performance, spark plug fouling, hard start-
ing, and increased emissions. Carburetor adjustment by 
an authorized service center will improve performance and 
allow that this engine meets EPA (Environmental Protection 
Agency) and California ARB (Air Resources Board) emis-
sion standards.  An engine adjusted for high altitudes can 
not be run at 2000 feet or lower. In doing so, the engine will 
overheat and cause serious engine damage. Please have 
an authorized service center restore high altitude modified 
engines to the original factory specification before operating 
below 2000 feet.
