Rochester 1, 2 & 4 barrel electric choke. This thermostat can also be used on the marine 2gc type of carburetor where the choke is mounted near the top of the carburetor. Also works on most Mercarb carburetors.

FEATURES:

  • Exact original equipment replacement
  • Housing mate with original equipment connector
  • Automatic operation in all temperatures
  • Durable, over one million field tested
  • High performance, restoration, street/strip, marine, and custom configurations available
TECHNICAL:
Works on the older 2 jet where the hot air tube connects to the center of the thermostat.
Works on the older Rochester 1 barrel carburetor where the hot air tube connects to the center of the thermostat.

The winding on this choke may not match your old thermostat.

Do not use a gasket behind the thermostat. The thermostat uses the back plate to ground.
Connect to 12v source when the key is on.

SPECS:

  • Looking at coil = rotates counter-clockwise when heated (choke opens / lean)
  • Choke shaft = rotates clockwise to close (choke closes / rich)
  • Cap diameter = 2.25"
