is a carburator a carburator if spelled correctly, or are some better than others?

Answer 1

They are all different (Carburetors) the important thing is that you match the correct size to your engine I haven't seen too many Holly double pumpers on four cylinders. but you just can't throw a larger carb on your engine and expect more power. You need to seek advice from the boys at the local speed shop.

Answer 2

Some carburetors are better than others, but most of them can be rebuilt and tuned to whatever engine they are on. The most important part is to choose the right size carburetor for the engine.
