austinsailor Posted January 24, 2016 Report Posted January 24, 2016 I have friends who have a 49 3/4 Dodge, I think that would be a B2B, and needs a new carburetor. I found them the truck a few years ago, now I'm going to try to locate a carb. I have no idea if the one on it is correct, but it would help if I knew the correct number. Most, if not all, of those old B&B carbs had a number on them, maybe 4 digits (numbers and letters) long. If I had that number it would help find the correct one. Anyone know what that might be? It might sound like a long shot, but once I located the correct # for my 36 Desoto Airflow, it didn't take long to find an NOS carb for it. I'm hoping I can do the same for their truck. Quote
Jeff Balazs Posted January 24, 2016 Report Posted January 24, 2016 Is this truck a 3/4 ton model? If so then the model is a B-2-C. Does it have a fluid drive? or is it a 3 speed? This affects the model of the carb. Jeff Quote
Merle Coggins Posted January 24, 2016 Report Posted January 24, 2016 (edited) A '49 3/4 ton truck would be a B-1-C and wouldn't have fluid drive. That didn't start until '50 in the B-2 trucks. I believe you need a DTE1 carberator. Jeff and I have DTG1's to work with the FD. That would work too but you'd want to disable the dash pot. Edited January 24, 2016 by Merle Coggins Quote

JBNeal Posted January 24, 2016 Report Posted January 24, 2016 I looked thru my info, and the best I can tell is that if ya stick with any model BB carb, it should work. My '48 has a '55 Plymouth 230 that had a problematic E7T1 carb I rebuilt annually. I snagged a D6G1 carb off of eBay several years ago, put a DTE1 carb kit in it, and the carb problems I had went away. I bookmarked The Carburetor Doctor from a previous discussion and thought I had a Carter manual that spelled out the various carb number differences but cannot seem to locate it, so maybe I confused that manual with a rebuild sheet that came with an older carb kit. I am assuming that the different carb numbers represent different jetting among the BB models. I checked my spare motors, and none of them had a legible carb number on the air horn; the '53 Spring Special has a DTE2 carb, on an engine that appears to be original to the truck. The parts book shows that the B-1-B & B-1-C used the same carb, and the B-2-B, B-3-B, B-4-B, B-2-C, B-3-C and B-4-C used the same carb (non-fluid drive), so I reckon ya need a DTE1 or equivalent Quote
