Replacement assembly with "Flat" shaped terminal. The flat terminal allows use of standard spade type electrical connection.
Rochester Varajet carburetors.
When 12v power is supplied to the choke and the element heats up, the bi-metal coil tightens up. When the coil cools down, the coil un-winds.
Thermostat diameter: 2"
Choke coil spring can be carefully removed and flipped over and re-installed. This will allow coil to rotate in opposite direction if needed.
Clocking position (location of end of bi-metal coil spring) may be different than photo.
Note: Pigtail connector # 1331 or OEM connector can be used for a factory look, but the connectors locking/unlocking mechanism will be lost.
