These adapters offer improved hood clearance due to theeir slim design, and orient the carb parallel to the crankshaft for improved fuel distribution. Gaskets not included. No machining required. 

    Please read the Classic Inlines tech article Selecting the Right Carb before buying a carburetor or an adapter.  Make sure you check out our Air Cleaners and Cold Air Induction Kits. We also offer an air cleaner base plate adapter, so you can mount any 2V/4V air cleaner on your Weber carb. 

    In the photos, you can see how the insert slips into the adaptor after the adaptor is mounted to the manifold using the stainless steel Allen head cap screws. As such the insert not only funnels the air into the carb bore, it also conceals the Allen head screws to improve airflow and horsepower.
