General information about this item

Product info
The main jet 110 (Part No. B7-03-0481) determines the fuel flow rate in the main system of the BMW 700’s carburetor, thereby ensuring a defined mixture under load. When overhauling the carburetor, a worn or modified jet should always be replaced to ensure the engine runs with factory-spec fuel metering and stable power delivery.
