Float Setting; Fuel Level - Wisconsin VH4D Repair Manual

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