Checking the spark plug
– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.6 - 0.7 mm (0.024" - 0.028"). If the gap is too wide or too narrow, adjust it. If the spark plug is clogged with carbon or fouled, clean it thoroughly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock). | |

Suction head in the fuel tank
– The felt filler (1) of the suction head is used to filler the fuel required by the |
|
carburetor. |
|
– A periodical visual inspection of the felt filter is to be conducted. For that |
|
purpose open the tank cap, use a wire hook and pull out the suction head |
|
through the tank opening. Filters found to have hardened, been polluted or |
|
clogged up are to be replaced. |
|
– Insufficient fuel supply can result in the admissible maximum speed being |
|
exceeded. It is therefore important to replace the felt filter at least quarterly |
|
to ensure satisfactory fuel supply to the carburetor. | (1) |
