Abstract
A vacuum break assembly for the carburetor of an internal combustion engine that acts in connection with a thermostatic controlled control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. The device includes a valve with a precision bypass which is protected from clogging by a filter element encapsulated by a member which also forms a part of the valve seat.
