A flange provides a secure, rigid position within the carburetor housing unit. It's particularly important when it comes to allowing a bearing to rotate within a contained and clean environment.
The mount flange is used as an adaptor to a car's, ATV's, dirt bike, or motorcycle's carburetor. It's also used on the sleeve or spigot mount carburetor to flange mount manifolds too.
On that note, what exactly should you be looking for when it comes to mount flanges to ensure your vehicle's wellbeing from under the hood?
Searching for the Best Carburetor Mount Flange for Your Car
- Dissecting the Features of a Carburetor Mount Flange: Your mount flange should be a rib, collar, or flat rim that strengthens, attaches, and mounts your carburetor properly to your vehicle's engine bay. It maintains the part's position and makes sure it's efficient in doing its job (which, in this case, is carburetion). The best mount flanges will keep your carburetor affixed into place so that it doesn't leak when it blends your fuel and air in an internal combustion engine.
- Measurements of the Flange: Have your damaged flange properly measured or look up the part's specs on the Internet if you want a precise measurement that you won't get from a measuring tape. This will ensure you proper fitment. The ecommerce websites where you can find replacement flanges typically include measurement tables that you can use to match your carburetor with the right flange size. Or just have a mechanic figure out the right flange size for you by their experience.
- Dimensions, Diagrams, and Adaptors: Although going for a universal fit mount flange seems like the best and most practical thing to do, most of these flanges don't really have a perfect fit for every last car type. You may need to also buy a special adaptor for them to make them fit perfectly. As much as possible, purchase a flange that matches your model and make of vehicle. Know the dimensions of the flange, its bolt hole center, typical carburetor size, flange throat depth by grams, carburetor spigot diameter by inches, and carburetor bore size.
- Fuel Injection versus Carburetors: Vintage cars mostly make use of carburetors and, in turn, mount flange for those carburetors. This is because fuel injection technology exists that do a better job at blending air and fuel together. If you have a diesel vehicle, you're also likely to use a carburetor to induce carburetion or the consequence of proper air and fuel blending. This part is also common in motorcycles, by the way. Fuel injection is better than carburetors, but if you have a vintage machine, you have no choice but to deal with your carburetor.
