The engine will not start or will stall, as no fuel is being supplied to the carburettor's venturis for mixing with air.
Most modern petrol cars use fuel injection, which does not require a carburettor or float chamber. However, they are common in classic cars, motorcycles, lawnmowers, and small engines.
The fuel tank is the vehicle's main, large storage container. The float chamber is a small, secondary reservoir inside the carburettor that precisely meters fuel for the engine.
