Rochester 2 & 4 Barrel Electric Choke Thermostat

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.

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.

Nice to have a product like this available. Restoring/Rodding a 56 chevy wagon and did not care to use the original exhaust manifold riser tube. Fit is perfect, No hassle purchase with fast shipping.

This is my first carburetor rebuild and Mike helped advise me on this item and helped on lots of other questions relating to the rebuild.

Worked wonderfully on a 1979 Glastron CVX-17SS with Mercruiser 140hp 3.0L engine. Fixed all my starting problems. I had to wire the positive of the choke to the positive of the coil. Very pleased with this electric choke. -andy

The choke thermostat arrived quickly and went directly in place of the original one and has worked flawlessly since. I couldn't be happier

Used carb kit in past worked grate will install choke in spring

This thermostatic choke replacement is working correctly on my 5.0 Mercruiser with a 2 barrel Mercarb. The boat now starts perfectly and warms up well every time. Much more cost effective than original part and trusted mikes more than the Amazon options.

Great price great service to Northern Canada

Worked like a charm and fast shipping. A+++++++
