Assuming you are working on a motor made around 1975 (you did not say) then yes, the float bowl is the same for the 9.9Hp as it is for the 15Hp.

Sorry, its a 1978 15hp, carb that needs the bowl. Kinda hard to find, so looking for options. Thanks, buy the way the wheel has been reinvented in numerous sizes, colors, and designs. Mankind is always looking for bigger and better.

The 1978 9.9Hp float bowl will fit a 1978 15Hp carburetor.

I am assuming your question on points to CDI is not for this engine, since I believe that engine already has CDI.
