4.3.6.4 Setting the throttle friction
The carburettor throttle valves have tension springs that pull the valves into the full
open position should the throttle cable snap. The moment of the springs on the
throttle valve levers is compensated by the friction of the throttle lever shaft in the
plastic clamps and a tension bungee. Journal bearing friction can be set by the front
attachment screw.
First, the running surfaces of the plastic clamps are greased slightly (journal bearing).
Then the bearing attachment screws are screwed so tight to compensate the
retention moment of the springs. The throttle lever must not be drawn forward by the
springs but it should also not be difficult to move. The correct tension must be
checked in various throttle settings.
