My 52 DeSoto Firedome with the low deck 276 Hemi uses a Carter WCD 884S water cooled ( or warmed ) carburetor. The coolant flows through two tubes - one from the back of the water pump bypass, through a passage in the base of the carburetor, and back into the cooling jacket at about the Number 2 intake runner. I ended up twisting one up pretty bad to the point it is now completely unusable. Corrosion had cause the 1/2" inverted flare nut to seize onto the tube which I believe is made of a copper alloy. The other came out ok. I was able to loosen them enough to remove and did a good cleaning. I plan to re-create the broken tube using some 1/2" soft copper and flaring both ends. The inverted flare nuts are available through a local Fastenal distributor so that's not a huge issue other than I have to get a 1/2" tubing bender and make an almost 180 degree bend. I do have a technical question though... If I plugged the water outlet holes and ran the car without the water through the carb base I'm sure the car will run fine. I'm concerned about fuel boiling off and vapor lock. Does anyone in the forum have any experience with this? I've seen other folks use a more modern carb without water cooling with no negative reports. Any thoughts from the forum?
