Celebrity V6-173 2.8L VIN X 2-bbl (1985)
Thermal Vacuum Valve - Carb: Description and Operation
Choke Vacuum Break-Vacuum Delay Valve (CVB-VDV)
When a sudden increase in vacuum occurs, the orifice within the valve delays the vacuum to the carburetor vacuum break. This delay is caused when
higher vacuum is sensed by the valve and length of delay is dependent of the difference between the high and low values. The greater the difference the
greater the delay.
