Specifications

when startin{~ the engine. The choke valve is of a =semi=automa-

tic

type, having a poppet valve incorporated in its design, which

is controlled by a spring. The poppet valve opens automatically

when the engine starts and admits air to avoid over-choking or

flooding of the engine. The mixture required for starting is con-

siderably richer than that needed to develop power at normal

temperatures. As the engine fires and speed and suction are in-

creased, the mixture ratio must be rapidly reduced. This change

is accomplished through adjustment of the choke valve and the

automatic opening of the poppet valve to admit more air when the

engine fires.
