Part Number:TH1051
Rochester 1, 2 & 4 barrel electric choke. 2 1/4" diameter. 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.

Works on the older Rochester 1 barrel carburetor where the hot air tube connects to the center of the thermostat.

While the winding on this choke may not match your old thermostat, this thermostat winds counter clockwise when heated up and you are looking at the coil.

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.

Goodbye cruddy riser tube
I bought this in hopes that my 55' chevy 210 would finally have a proper working choke. It always seemed like I'd have to keep readjusting the choke at least once a week during the summer in order for the car to start or open the throttle and push up the choke to start. After my wife tried to go somewhere one day and I wasn't home to help start it by pushing the choke lever up, I figured this may fix it, and it did! Used on a factory Rochester 2 barrel with the heat riser tube going in the side of the thermostat housing. Pulled off the old one and the gasket, put the new one on with no gasket, wired the new thermostat to the positive side of the generator (not an alternator) and after 2-3 minutes the choke is kicked off and you are ready to go. I bent the riser tube in half to block the exhaust temporarily until I am able to plug the exhaust manifild. I've been happy ever since. Also, the winding on the inside of the thermostat contains a longer piece of wrapped metal compared to factory and rebuild kits with the hot air thermostat spring replacement. Ditch that piece of junk hot air riser that takes 15 minutes to warm up and buy this with no regrets and no hassle.

Great so far
Works just like it's supposed to on my old Rochester 2-barrel marine carburetor. Easier than messing with the corroded old pipe, fittings and questionable threads on the original hot air choke. Took all of 15 minutes to install. You'll need to provide your own power wire, and remember to leave the gasket off the choke housing because this unit grounds directly to it.

Installation was simple. It dropped right in into the choke housing. One wire hook up makes it even easier.
