RE: Driveability Problem

Hi – I want to make sure that my Carter BBD carburetor has the proper size jets. The factory manual calls for jet # 120-294S but does not indicate its size. Unfortunately, none of the jet suppliers use the this number – they only go by size. Does anyone have information on the size of the standard jet for the Carter BBD used on a 1965 273 A/T? Thanks

Starved for fuel, plugged lines, fuel filter, weak or bad fuel pump, float in carb not set right.

I'd start by testing how well the fuel pump, pumps. One way to check the pump is to disconnect the fuel line at the carburetor and place the end of the line into a container. Crank the engine to see if the pump is pushing any fuel through the line. Strong steady spurts of fuel mean the pump is working. No fuel or a weak stream means a bad pump, a plugged fuel filter, fuel line blockage or no fuel in the tank.

If it pumps lots of fuel and seem strong I'd then check the float in the carb. It could be set too low and the car starves for fuel, or it could be plugged port for the fuel into the bowl that would cause it to be starved for fuel.

Both are easy to test and can tell you a lot.

Goodluck

Perhaps just perhaps mind you the coil may not be giving you the fire it should and during acceleration is not lighting all the cylinders as it should. Since I agree that it sounds like a rich condition as it should be at that point I am left wondering why it's not lighting.

Good luck

My 65 Barracuda with a 273 engine starts and idles very well. When accelerating it runs rough but smooths out at a constant speed. Points, timing, valves are all dead on. It has a new, not rebuilt, distributor and spark plugs and wires are new. The Carter BBD carburetor was recently completely rebuilt by a reputable carburetor shop but it did not correct, change or improve the situation. The repair shop where the car now is has gone through everything and they feel that it is still a fuel problem. In fact, they feel the engine is getting too much gas (though the fuel mixture is adjusted to spec and I have noticed no black smoke from the tailpipe). Given all the facts above, does anyone have any suggestions? Am I missing something?
I have an old Stromberg WW3 that I will have the shop put on so as to compare how it runs with the Carter. I asked the carb shop if the jets could be bad but he said no. In any event, jets are apparently not available for this carb. Thanks for any help. Bob from Maine
