when starting the engine. <strong>Th</strong>e choke valve is of a =semi-automatic"<br />
type, having, a poppet valve incorporated in its design, which<br />
is controlled by a spring. <strong>Th</strong>e poppet valve opens automatically<br />
when the engine starts and admits air to avoid over-choking or<br />
flooding of the engine. <strong>Th</strong>e mixture required for starting is considerably<br />
richer than that needed to develop power at normal<br />
temperatures. As the engine fires and speed and suction are increased,<br />
the mixture ratio must be rapidly reduced. <strong>Th</strong>is change<br />
is accomplished through adjustment of the choke valve and the<br />
automatic opening of the poppet valve to admit more air when the<br />
engine fires.<br />
