Okay, I've got a vintage JD 111 mower with a 28B707 engine that is supposedly 9hp. I've got a 287707 engine that is supposedly 12hp.
Now, when researching parts and pieces, more often than not, the parts are interchangeable. Visually, the engines are identical.
So how does B&S go from 9 to 14 or 15hp with the same engine? Bore? Stroke? C/R? Carb/intake?
Thanks.
