I am impressed by the cooking. It made me hungry (and I am vegetarian).

You can cut away the narrow part inside at the venturi; this will allow more airflow. However, it will result in poorer performance when not operating at high RPM, as the fuel will not be so evenly drawn out and vaporised. For a car to be driven on the street, it is often not a good choice.

If the carburettor is your main obstruction to better performance, then probably you are arriving at the time to upgrade.

The real problem is usually airflow. Only so much air may pass through the venturi, unless you make it bigger. If you add too much fuel, the ratio of air:fuel will be too rich for good performance.

Maybe slightly bigger jets could work - but will it give enough power?
