Cleaning the fuel lter
The fuel lter of the suction head is used to lter the fuel required by the carburetor.
Perform visual inspection periodically.
1. Open the tank cap, use a wire hook and pull out the suction head through the
tank opening.
2. If the lter is hard or clogged up, replace it.
3. After checking, cleaning or replacing, x the fuel lter onto the fuel pipe with the
hose clamp. Push the fuel lter in all the way to the bottom of the fuel tank.
NOTE:
• It is recommended to replace the fuel lter at least once every three month to
ensure an enough fuel supply to the carburetor. Otherwise an insufcient fuel
supply may cause the engine defects.
Checking the spark plug
CAUTION:
• Never touch the spark plug connector while the engine is running (danger of high
voltage electric shock).
The gap between the two electrodes of the spark plug should be 0.6 mm - 0.7 mm
(0.028” - 0.030”). If the gap is too wide or too narrow, adjust it. If the spark plug is
clogged or contaminated, clean it thoroughly or replace it.
0.6 mm - 0.7 mm
