Moparfan283348 Posted March 5, 2016 Report Share Posted March 5, 2016 Another question I have about the 46-48 Dodges is about the carburetors. I have learned that the Dodge cars that have the three-speed with fluid coupling have a carburetor with a dashpot to slowly bring the engine back to idle to prevent it from stalling. What do these carburetors look like and what would their number be? Also, what is the easiest way to identify these carburetors? Thanks in advance.

traveller816 Posted March 5, 2016 Report Share Posted March 5, 2016 Can't answer for the Dodge but as my 42 Chrysler is equipped with 3 speed manual with fluid drive I'd assume we share the same carb. Mine is a Ball & Ball Carburetor by Carter. I will endeavour to post a couple of pictures of the identification for you but they are on my phone. Hope this helps. I have also heard them refered to as B&B. Quote Link to comment Share on other sites More sharing options...

DonaldSmith Posted March 5, 2016 Report Share Posted March 5, 2016 My carb, for the semi-automatic transmission, has a kickdown switch and dashpot. A carb for a three-speed transmission would not need these, with or without the fluid coupling between the clutch and the engine. "Fluid Drive" refers to the coupling, not to the type of transmission. Quote Link to comment Share on other sites More sharing options...

mopar_earl Posted March 5, 2016 Report Share Posted March 5, 2016 I'm pretty sure fluid drive cars (3spd with fluid coupling) had dashpots too. The semi autos had electric dashpot while the fluid drive was strictly mechanical. I have a parts manual, I can look up the exact carb your car should have. As long as you don't let off the throttle suddenly at low speeds, the dashpot isn't needed. Mines not working and I only had it stall once. Backing in the garage I left off the throttle too quickly and it stalled. I have a lip at my overhead door and it requires some power to roll up over it and than you're going too fast and need to hit the brake. I've learned to keep the car from stalling doing that until I replace the dashpot cup. Earl 1 Quote Link to comment Share on other sites More sharing options...
_shel_ny Posted March 5, 2016 Report Share Posted March 5, 2016 As stated the Stromberg BXVD-3 with dashpot would be correct. Not to be confused with the BXVES-3 used on the vehicles with a gyromatic transmission. It has a dash pot solenoid. The BXVD-3 marking is on the side of the carb toward the head. The dash pot rod is on the side where the line from the fuel pump connects. 2 Quote Link to comment Share on other sites More sharing options...

mopar_earl Posted March 5, 2016 Report Share Posted March 5, 2016 Dodge typically used Strombergs. Carters on the other divisions. Earl Quote Link to comment Share on other sites More sharing options...
