Dashpot Type of Carter BB
This picture illustrates where to find the carburetor number and also the difference between a carburetor with and without the dashpot. The dashpot type of carburetor usually was placed on vehicles with automatic transmissions. Can the dashpot type be disconnected, or replaced by a non dashpot type? This would not be recommended, but also depends on the type of transmission. If the transmission is a semi-automatic, then the car may stall when slowing or coming to a stop; that is what the dashpot prevents. Even when the dashpot solenoid is disconnected, you would still need the presence of the kickdown switch used with Fluid Drive, Hy-Drive — whatever — on that particular carburetor. If the tranny is manual, then it never had a dashpot or a kickdown switch to begin with and disconnecting it should do no harm. Don’t ask me why Chrysler determined that their system had to be electrical, because most dashpots used from the ’50s on up were passive. Perhaps it has to do with the semi-automatic (as opposed to fully-automatic) nature of their transmissions back then.
Here is a crossover list of dashpot carburetor and which dashpot they used.
Please note that this is only a list of what we now know about. Some could be missing.

We have 4 different types of chokes, Intregal, Divorced, Electric & Electric Conversion.
The integral choke is mounted on the carburetor, either near the top, or near the bottom. The illustration shows the choke mounted on the top of the carburetor. The thermostat is heated by a heat tube that runs down to the exhaust manifold. The heat tubes heats up the thermostat and moves the choke valve to the open position. A vacuum passage in the carburetor feeds up to the choke housing and helps pull in the heat from the heat tube. Some of these chokes will also have a hot water jacket running through, or on the thermostat to facilitate heating.
The divorced choke typs has the thermostat mounted in the intake manifold instead of on the carburetor. In this illustration, the arrow points to the thermostat which is covered by a metal shield. A rod connects the thermostat to the choke lever, which controls the choke valve to be opened, or closed. As the intake manifold heats up, the thermostat mounted, expands, opening the choke valve.
This is a typical electric choke mounted on the carburetor, which is integral. In this case there is one wire on the choke thermostat. This is the 12v source, which all electric chokes use. The thermostat is grounded via the carburetor itself. Some electric chokes will have a 2nd wire (ground wire), which is connected back to the carburetor. When the key is on the thermostat is heated up, opening the choke valve.
|Electric Choke Conversion
This is a typical electric choke conversion kit. This is used to convert an integral, or a divorced choke to an electric choke. These choke kits come with a temperature sensor that bolts on to the intake manifold, which provides more accurate choke control than with an electric choke without the gauge. The electric choke conversion kit is not used for a manual choke conversion. The choke housing must be in place in order for it to work.
