It's intentional. There is a drain on the manifold with a check valve that opens when engine vacuum ceases e.g when the engine stops. This is to prevent raw gas that collects in the manifold washing into the cylinders on the next start up. Clear as mud? Regards John Harley

Dear Schneff:
That is symptom of clogged main jet air bleeds on the Stromberg carburetor. Concurrent should be extended cranking when hot. The anti-flood prevents the manifold from filling up with gasoline and backfiring. To fix it requires disassembly by an experienced carb rebuilder like Daytona or the Carburetor Doctor because it requires a special jet wrench and a hammer. Eventually the car will start running poorly, and you could soak the main body in lacquer thinner or PPG DX440 which may help a little bit. But do not soak extensively in strong reactive solvents like Aerocarb.

Thank you both - making more sense now. My gut was telling me I may be looking at a carb rebuild, thanks no doubt to the wonders of ethanol. The car is all original and I want to get the same carb back. Do those that you mentioned do that, and any idea of the cost ?
