Working for a Mikuni distributor, I've had the opportunity to open up and examine hundreds of brand new, fresh-out-of-the-box carbs. On a 24 mm Mikuni card, the distance between the gasket surface and the float should be 1 inch. The Carburetor’s float height serves a very crucial purpose for how your carburetor reacts to the fuel it is given.
