what motor are you talking about? The only carb'd yota motor is a 4cyl and has a manifold (1). Those numbers arent the carb numbers.


CARB=California Air Resource Board, not abbreviation for carburetor.

As 4Crawler mentioned, it is the number CARB gives to a product once it verifies it street legal for use here in CA. W/o the numbers to punch in at the smog check time you will fail smog for any aftermarket add-ons.

More than tread lightly. Leave it like you were never there, nor anyone else.
