Abstract
A carburettor controlled by a pulse width modulated duty cycle operated solenoid 78 has a main metering rod 38 and an idle bleed valve 64 spring biased against a bracket 44 carried by the solenoid armature 70. The armature is spring biased to a rich position against an adjustable stop 74 and is pulled by the solenoid coil to a lean position against a portion of the solenoid coil assembly. The entire coil assembly is biased by spring 106 against a stop 104 which is adjusted to establish the lean position of the metering rod and bleed valve. <IMAGE>
