Originally the Model A left the factory without an air filter. This carburetor has had internal modifications to improve the performance of the original carburetor when running one of the aftermarket air filter assemblies. A normal carburetor will tend to run rich with an air filter. All new, a core is not required. U.S.A.
SAME PARTS AS REGULAR CARB EXCEPT THE VENTURI IS DIFFERENT
Filter assembly simply clamps to the OD of the carburetor throat with a rubber hose and hose clamp. Puts the filter above the carburetor so it is not affected by gas dripping into the element.
Element comes pre-oiled and can be cleaned and recharged when necessary. Filter cleaner and oil can be purchased at your local parts store when this is necessary. U.S.A.

You will need to run a pump and regulate your pressure to 2-3 pounds. There have been issues in the past with using these Weber carburetors with Mallory and FS distributors due to the advance curve being too slow in advancing.
They need lighter springs to bring the advance on sooner. To verify, remove your Mallory or FS and replace with a stock style distributor and see if the issue goes away.We recommend purchasing one of the Nu-Rex timing kits so your timing is set up properly giving you the ability to check with a timing light, the part number A-6252. 25 degrees max advance and all advance
