  • Engine: Driveability issues

    Hello everyone, I have a 53' commander and I'm having an issue. The car will start and run after sitting overnight, but when started, runs normal for about 20 seconds, then gets a high idle, then dies immediately. It will not start back up unless I let it sit for about 20 minutes. Any input would be greatly appreciated.

    Sounds like you are running out of gas! check fuel filter and fuel pump. a trick i use is a plastic fuel tank from a mower wired to cowl as temp. source. pump dumps into plastic bucket. somewhere their is a spec for pump volume, a pint in 20 seconds or something like that. Luck Doofus

      Ok I'm going to try that today, fuel filter does have very little fuel, maybe it's clogged. Thanks

        You may be drawing air in or have a restriction. Have the fuel lines been replaced, both flexible and solid? Sometimes you can get a pinhole that will draw air in but be hard to find. These are often at the clamps on the line.

          I also believe that it is starving for fuel, but it sounds to me like the problem may be at the tank. Overnight, the gas trickles into the line and it will run on that for 20 seconds or so, then no more fuel comes from the tank. If you can blow back through the line with 10 or 15 pounds of air to clear the line. If it runs after that, you may have to pull the tank and clean it, or have it cleaned. Good Luck with it.

            Make sure the gas cap is the vented type.

              So I replaced the fuel filter, no change. Disconnected fuel line from carb and ran into a clear jar. Plenty of fuel delivery it seems. I'm assuming carb is just done for? I was able to spray ether into it and keep it running. My guess is there's a blockage in the carb potentially?

                At least you have it narrowed down to the carb. It is most likely not "done for". If it ran good before this , it should be good, cleaned up and rebuilt.

                  The Original and from "the Day" needle SEAT Fitting, had very Fine Screen inside, that would clog, Quit and then slowly let Fuel seep in and then Run for a bit, that WILL Fool you!

                      Just to point out you can remove the needle and seat on that carb (takes about two minutes if you dwawdle) without disturbing anything else. It just unscrews where the fuel line goes in. A little cleanup might get you up and running with really minimum fuss.

                        I had an old car with an original gas tank. The tank began rusting, and when the engine was running, the debris would be sucked into the fuel filter and cause the car to die.
                        When the car was turned off, the debris would slowly settle back down, and eventually allow it to be started again. Had to replace the gas tank, and problem fixed.

                          Not to worry if you own a Studebaker, there are NO in-Tank Filters or "Sock's".
                          Only the slim possibility of a Large object like a Rag or something getting sucked onto the Fuel Line Output Tube.

                            I'm going to rebuild the carb, I took it apart and cleaned what I could, but some of it is rusty and oxidized or something. I may have also lost a tiny little ball bearing from somewhere in there haha. It's not the one under the plunger thing, that's a little bigger ball them the one I lost

                              Who hasn't lost that little steel ball? Wonder if #4 birdshot would be an appropriate replacement?? Won't work without it! Does sound like fuel delivery. My 57 Clipper had the fuel line nearly pinched shut where it was foolishly routed between the frame and terra very firma. Replace and reroute. Disconnect the fuel line at the pump and see if you can easily draw fuel from the tank. If not the problem is in the tank or the line. Sometimes the pickup inside the tank is completely clogged with rust and crud (or tank sealer) If you can pull gas up easily, it is the pump fuel line, fuel filter or carb. It sounds like you can start it, use the gas out of the float bowl and it quits, So, why should it start after 20 min??? The float bowl would still be empty. My John Deere was the most cold blooded thing years ago and it finally annoyed me to the point of fixing it. Got a carb kit which I did not need 'cause there was crud in the inlet with only a pin hole to allow gas into the carb. The rest of it was clean as can be--very strange. (just bought one of those little balls for $3 which it looks like I didn't need. Of course there is always the needle stuck in the seat or the float failing to drop. Sometimes a little percussive adjustment can shake them loose.
