Hi all,

I'm new here but have owned slant sixes for 35 years, and have normally not had too much trouble keeping them running. However recently I've been baffled. I have a 1982 Dodge D150 that has run pretty well since I've had it (about 5 years). Recently it developed some driveability issues where it would randomly flood out after driving for a while (maybe 5 miles, maybe 25 miles). After stopping and pulling the air cleaner you could see the fuel percolating into the carb throat. I'm thinking needle and seat, stuck float something of the sort.

I decided to put a kit in the carb. It's never run again. It cranks right up and immediately dies. I've meticulously disassembled and re-assembled the carb twice paying close attention to the diagram to make sure I didn't do something wrong. Note: The accelerator pump check ball and weight as well as the float hinge retainer were missing originally which I replaced. I even confirmed there are no manifold leaks with a smoke can.

It's acting as if no fuel is reaching the circuit... but the float bowl is full and float is adjusted according to spec. Baffled I removed the carb and disassembled once more and started blowing out passages with brake cleaner. I noticed something suspicious. Is there supposed to be a hole at the very top of the emulsion tube right where it's pressed into the carb housing? This is a Holley 1945.

I tried uploading an image but am getting an error.

I have another one of those carbs if you want to take a chance on it.
Sorry, I cannot be of more help on your specific situation.

I got a car to run on an engine that was sitting ~25 years. Send me a message if you are interested in it.

Thanks, Greg

I got a UREMCO reman carb and the trucks running great. I haven't heard great things about remans so "whew"!

I didn't take the new one apart to confirm, but I'm pretty sure that tiny hole I found in the very top of the emulsion tube wasn't supposed to be there. My only guess is it was corroded, and when I cleaned the carb to rebuild I opened it up, and it never ran again.

This may be controversial but you can have a stock slant six run better than it ever has by running a 38 x 38 DGES/DGAS Weber (or Weber clone) carburetor. It is not necessarily a simple swap, but I am running these carburetors on both my vintage pickup trucks (1960 Ford F100 223 I6 and 1967 Dodge D100 /6). In both cases I am running them on the original 1 barrel manifolds with adapters. I made the adapters but I believe you could probably source an adapter or parts to make one. Be aware that the Weber bolt pattern is different from most domestic 2 barrel carburetor bolt patterns.
In addition you will have to make the throttle linkage work but they come with parts to convert to electric choke so no more choke cable/manual choke and you also need to decide whether to run a Weber air cleaner or adapt the stock one (what I did).
Also a good cleaning and float adjustment is crucial as bits of metal from production are typical and float level is apparently not factory set. The jetting that comes standard is spot on though.
I am running the clones. They are available online (say ebay) for under $100.
They run and accelerate great. No "dead spots" typical of those old 1 barrels.
So maybe not "simple " (see my signature ) but we'll worth it.
