Carburetor (1.1 Liter Engine)

Carburetor idle system is leaned out and special features are incorporated which make possible additional idle mixture adjustments over and above those manufactured into the carburetors. Leaner carburetion is possible because of more accurate metering and better distribution achieved by two carburetors. An additional air/fuel mixture valve assembly is attached to balance tube of intake manifold. A mechanism is incorporated into mixture valve assembly which allows an additional air/fuel mixture to be drawn into combustion system when decelerating.
