Default Re: Identifying carburetors

as uncle max stated, the throat is slightly bigger on a 48. so, some of the guys with big cubic inch motors trying to get big horsepower like the 48's. the 97 is more common, and more popular with many because it is a simple carb with a good rep for reliability. thats my thoughts on that, and i will let the real carb people tell you whats wrong with your holly
