FDNY 343 Posted March 26, 2019 Share Posted March 26, 2019 Does anyone know what this rectangular box is at the base of my Zenith Carb. there is a copper tube that runs down to the exhaust manifold. I was wondering if it was some kind of automatic choke valve.... once the motor heats up maybe a spring or something opens in base of Carb???

41chevy Posted March 26, 2019 Share Posted March 26, 2019 Thats a carb heater between carb base and intake. Prevents icing during warm up and fuel puddling during extended idling (keeps the fuel vaporized) Ford and some Mopars ran engine coolant threough a spacer plate to do the same thing Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/56359-1955-en707-gas-~-carb-plate-question/#findComment-419034 Share on other sites More sharing options...
FDNY 343 Posted March 26, 2019 Author Share Posted March 26, 2019 Someone on a B Model page said it was a Vacuum Operated Governor? They pointed out that the screws have security holes in them, I haven't taken the front plate off yet because I didn't know what if anything could possibly come popping out on me....lol....that's my luck 1 Quote Link to comment https://www.bigmacktrucks.com/topic/56359-1955-en707-gas-~-carb-plate-question/#findComment-419039 Share on other sites More sharing options...
