Trouble shooting
Replacing the suction head
The felt Þ lter ( G/5 ) of the suction head is used to Þ lter the fuel
taken in by the carburetor.
A periodical visual inspection of the felt Þ lter should be conduc-
ted. For this purpose open the tank cap, and use a wire hook
to pull out the suction head through the tank opening. If the
Þ lter has hardened or is dirty or clogged, replace it.
Insuf Þ cient fuel supply can result in the admissible maximum
speed being exceeded. It is therefore important to replace the
felt
Þ lter at least every three months to ensure a good fuel supply
to the carburetor.
