Air Intake System & Carburettor Heat (all J-Series)
7.9.1 Description
The engine air intake system comprises a cold air inlet in the lower cowl, a hot air muff attached to
the exhaust system, a mixer assembly mounted on the firewall and connected to a carburettor. The
mixer box incorporates the air filter, control flaps etc.
Carburettor Heat is activated by pulling the Carburettor Heat Control on the panel OUT. This opens
the hot air valve in the mixer assembly and permits hot air to flow from the muff into the carburettor.
