Air Filter - Husqvarna 333R Workshop Manual

3
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.
