Has anyone ever retrofitted a 12 hp into a #7? Can it be done without chopping the hood all up?

Yes but you'll have to leave the hood off.  :(

Sorry,  i don't think the hood would fit without being cut.  With trimming in a neat fashion I believe it could be made to look really good.  Best of luck!

In addition to hood issues, I think you will have crankshaft height differences, and the larger engine may interfere with the fuel tank.

If you want more horsepower, try finding a hm 100 or equivalent.  You get an extra 2 ponies and the package is exactly the same size.  Northern tool had some at one point, and Small engine warehouse had them under the "Formula" name tag.

 

Here is where I used a Formula engine to repower my MF8 when the engine blew a rod:

i had two MF7s  One was repowered to a 9 hp Tecumseh flat head... had to notch the hood and the left front hood support severely.  I used that one and put a 10 hp OHV Tecumseh in it... had to modify the air cleaner intake, and exhaust, but it would have fit with less cutting.
