    '54 mystery no-run condition

    I was trying to fire the '54 for the first time since last November. It starts with the starting fluid. Once it ran maybe 15 seconds. Now it only runs 2-3 seconds.

    It has gas, and there is pressure in the fuel line to the carbs. I pulled the top off one of the carbs, and there is gas in it. Not sure if it is the right depth. How deep should it be in the well? I can't find the carb rebuild instructions.

    I disconnected the fuel line and let the gas drain out, then started it again with the fluid. After it quit again, I opened up the fuel line clamp right before the carbs, and gas shot out.

    I'm quite stumped. There is gas, spark, and air. The only thing I can think is something is wrong inside the carbs. It ran great last fall though.

    Any suggestions?

      Really? I didn't know old gas could cause the car to refuse to run completely. Some of the gas is pretty old, but it looks and smells normal.

        Would you expect that draining and replacing the gas, including in the fuel bowls, would clear things up? Or will I have to rebuild the carburetors too?

          I would not rebuild the carbs, I would first try all new gas.

            Thanks, Jim. Worked fine with fresh gas. Now it is smoking to beat the band, but I think that is from the "top engine lubricant" that the starting fluid contains.
