Title: Automatic choke arrangement

Abstract: An automatic choke in which the choke valve is urged by a spring and can be closed at a temperature lower than a set value and opened at a temperature higher than the set value by by a choke-return diaphragm. The diaphragm is actuated by intake vacuum in response to operation of a temperature-sensing valve, thereby eliminating an expensive bi-metal unit, or a manual control to close the choke valve at the time of start-up.
