I am replacing the carburetor on my 1964 150 vbb. Both carburetors are Spaco SI 24/24e . The guy who sold me the bike said that it had been kitted, hence the bigger carb for the 150. My problem is when I pulled the old carburetor off, the air box gasket is different from the new air box gasket that SW sent me. So my question is which gasket should I use. I have pictures. The first pic is of the air box. The second pic of the two gaskets. Left old, right new. The rest are of the gaskets on the carburetor old gasket two holes, new gasket three holes. The old gasket covers the hole on the bottom of the carburetor, new gasket allows the hole to be seen. All comments welcomed, thanks.
