Carburetor
Power nozzle
The power nozzle is activated when the engine is operating at high speeds. To reduce the fuel con-
sumption rate and the pollution of the exhaust gases, the carburetors of the F60 are set lean. There-
fore, the air-fuel mixture becomes lean at high engine speeds, when greater output is needed. The
power nozzle supplies a richer fuel mixture at high engine speed to realize the optimal air-fuel ratio
to produce output.
