Location: ZH, Switzerland | I noticed a weak low load behavior. I began few weeks ago. When I was driving around 30 mph, flat road, I thought from the vibration and sound of the exhaust that not all cylinders are working. At higher speeds (50 mph) the vibration was away and the engine (exhaust note) was normal. At the journey to Loerrach I felt slight power loss uphills at about 60 mph from time to time (not steady). Last test ride I did - even worse. It stalled three or four times when coasting, heading into a traffic circle or to a stop or pedestrian crossing. Once at a stop with a signal I switched to N and pulled the gas pedal a little bit to get a little bit higher speed at the engine. When the signal enabled my direction I pressed D and accelerated. It only stumbled and was several times close to quit the service. After all I reached 30 mph and my Chrysli was running normal. Accelerating from 30 to 50 mph was no a problem.
Just before the starter said good bye the engine was difficult to start. When it fired after few seconds it died again. It was not possible to keep it alive with pumping the throttle.
Could be that the gas pump is defect either. But I guess there is water in the tank, gas pump and carburetor. I'm going to open the filter bowl as soon as I'll get the filter bowl gaskets. After that I'll try to remove the air horn to have a look at the bowls.
B the way: what's the difference of a 2314S and 2314SA? The Service Manual addresses two carburetors for C-71, C-72, C-73, C-70: 2314SA or 2367SA. What's the difference?
Happy motoring!
Dieter
FYI: I just ordered a CK-36 kit from the carburetor doctor

| The 2314SA is for 56 Chrysler C-70-72-73, the 2367SA is for the C-71 (Windsor) power package. (Different metering rods and accelerator piston assemblies). Sounds like the low speed circuit in your carb got clogged with a bit of dirt, do you have a Carter glass-ceramic filter on its fuel inlet? A lot of the original WCFB gasket kits have shrunk in size 5% or more. The large fuel bowl to air horn gasket is usually the worst off.

Thank you very much for your answers, Shep and Richard.
Richard: Yes there is a Carter glass bowl filter (small bowl) at the fuel inlet of the carb. As soon as I'll get the gasket set I'll remove the carb to partially disassemble it and I'll use gas and pressurized air to clean it. |

Location: ZH, Switzerland | Today I disassembled all three parts. The air horn, the main body and the throttle body. I didn't remove the shafts, but the other tid bits. I noticed a severe wearing of the primary shaft.
I removed the discharge cluster and flipped the main body and the throttle body to the backside to remove the throttle body screws. Something fell out of the boring below the discharge cluster... a needle and what else? I'm quite stupid I guess...
Happy Motoring!

It's not the inlet ball under the accelerator pump. The inlet ball is still in it's position.
It's the pump discharge needle in the connection channel between the check ball and the discharge cluster. I figured out which direction it should be (thanks to the manual on the page of the carb doctor, just to verify - I was thinking about it either).
Happy Motoring!

Location: ZH, Switzerland | Very "funny". Always on a sunny day I'll go in troubles with the running behavior of the engine. It appears like it'll starve in the low to mid rev area (under load). I noticed (when I warmed up the engine to let all the trapped air out after filling with cooling fluid) that the bowl only has some fuel at the very bottom, but not filled up to the top end. I noticed how little fuel sipped into the bowl at the idle speed so that I wondered that engine still was running.
I'm going to look around to find some 5/16" fuel hose to replace the rubber hoses between the tank and the fuel pump. If it doesn't cure the problem I'll find a solution for the fuel pump. But first I'll check if it's better when I'll remove the cap of gas tank.
I guess it's a Carter M 961 S fuel pump used on NE56- engines up to the serial number 27142. The serial number of the engine in my Chrysli is 23738. I'll check the pivot pin of the fuel pump for wearing.
You'll see - a lot of small work on my Chrysli...
Happy Motoring!

| Rubber hose between the tank and fuel pump would be an invitation to disaster. Put in stainless tubing and live longer. |

Location: Chestertown, NY ( near Lake George) | Actually Napa now makes a new rubber line that is designed for ethanol or diesel, supposed to be bullet proof, but a metal line is always better unless inconvenient to install or needs flexibility. |
