I want to put a 600 edelbrock electric choke carb on my 54 Chrysler New Yorker that has a 6 volt positive ground electrical system. Is this possible?
Do they make a 6v electric choke? If they do it won't care if it is + or - ground. If not you will have to make other arrangements. Easiest would be a hot air choke taken off the exhaust, I think that is what Chryslers had stock.
I'd suspect it might work, but not as efficiently as it would with 12 volts. With the choke adjusted properly for cold starting, it may never open fully at normal engine operating temperatures. Adjust it to open fully and it probably won't close sufficiently for proper cold starting. But if you feel like experimenting, just to prove or disprove a point, you might try heating the choke thermostat electrically and adding an additional source of heat. Depending on how things are laid out under the hood, you might try splicing the heater inlet hose and rerouting a section of it near the choke thermostat cover. Many older cars, I'm thinking Fords in particular, had a metal tab on the choke housing that held the heater hose up snug against the choke stat cover. On some models coolant was actually plumbed thru the choke housing to supply heat to the thermostat. You might also need to add a bit of a tin shield ahead of the choke housing to keep under-hood air flow from cooling the choke thermostat. Or you could also convert it over to a manual choke, but where's the fun in that?
I am bumping this thread from the way-back machine, it is a dilemma I will be soon facing. My '54 NYpD sat for 60 years, it has the Original Carter 2041S WCFB. This car was miraculously complete under the hood with the exception of the heat tube riser from the manifold and the choke thermostat assembly... I can try to find the original pieces on Flea-bay, and spend on a kit that is available for a 70 year old Carb with unknown condition, or I can go with an adaptor and a modern-ish fuel makin' happener.... I intend to keep the original 6V electrical system... Was the question ever answered for the OP if there is a 6V solution for the Electric choke? I am not opposed to setting up a manual system on a new carb, which would be my 2nd choice over making the old Carter serviceable again.
Depending on what your 12v electric choke draws in current @ 12 volts, you may be able to find a DC to DC module that will convert the 6v to 12v. Probably around $5-10.
You could just measure the resistance of the electric choke and add a resistor of the same ohm rating in series. This will give you the same current flow on 12 Volt as the choke alone on 6 Volt,.
I only adjust the mechanical exhaust fed choke on my WCFB’s enough to put the fast idle screw on the first step. I always let the engine warm about 1 minute. May take 2 pumps on initial cold start up. If you try a 12v on a 6v system like said above it will heat the choke body just slower. Setting the choke flapper only enough to get to the first step assures you’re not sealing off air to the engine. I’m guessing the fast idle will be the best and won’t fuel wash the cylinders. Good luck.
Here is a link to a reasonably priced 6 to 12 volt ISOLATED converter. https://www.amazon.com/DIGITEN-Conv...pcontext&ref_=fplfs&psc=1&smid=A10ZX1GHP13ZSF
Hi sorry for the late reply, had a death in the family and the car took the backseat. My choke housing, what is left of it appears to be exactly 2 inches.
