What does Rejetting a carb do?
Rejetting Explained Carburetors provide the right mixture via jets which are brass parts with small holes in them. The holes regulate the amount of fuel that goes through the carburetor. Bigger jets allow more fuel and smaller jets allow less. Too little fuel and the engine may starve or overheat at high RPMs.
