Fuel system
In addition to the fuel tank and carburettor, the fuel system
consists of the air filter, fuel filter and tank venting.
All these components interact so that the engine receives
the optimal mixture of fuel and air to make it as efficient as
possible. Very small deviations in the carburettor setting or
a blocked air filter have a large effect on the running and
efficiency of the engine.
The carburettor can come from several different
manufacturers on our models, but the function and
repair methods are essentially the same.
