D 24 failed to procede

Last Saturday, On the way to our breakfast run and while climbing a hill the Buick D24 roadster came to a stop. JB on his own believed he would soon solve the problem and sent his son Mat and his mother on to the gathering about ten miles distant. They in the D45. John found that the engine would only run with the slow speed needle closed right off and black smoke at that, but upon opening the throttle the engine would choke up and stop. He found the vac tank to be operating ok, No raw fuel to the manifold and on removing the carby bowl cover the level was as it should be .As the continual trying to get it to run and off the road soon had the battery flat, Help was called and the glorious D24 taken home on our trailer. So what went wrong. Perhaps you have worked out that the High Speed Jet had disappeared from its place hidden behind the air valve and as the air valve opened the high speed jet was now the size of the discharge pipe. In a emergency the end of the tube might have been squeezed together or a piece of wire jambed down to restrict the opening of the tube to simulate the missing jet. At home a replacement jet was fitted and all is well with the MARVAL carburettor again. Max Burke Nulkaba 2325 Australia

Glad you got it resolved, even if you had to take the trailer home.

Marvel carburetors...
