What's the difference between these two carburetors?  Will they both work on a Crosley?

Thanks 

Hoping someone that really knows the answer see’s your question.  Other carbs in the DY series the change in number is different jets and air flow. Such as DY9 - 90 CFM, DY10 - 100CFM, DY14 - 114 CFM. The A, B, C, … is usually external bolt on differences within a specific number series. If the linkage can be made to work it will probably run on a Crosley but it may not run as well as the proper carb.
