Hi all. I have a 33 inch Troy Bilt walk behind that needs a new engine. I've narrowed it down to a B&S 10.5 to 11.5 but dont know which charging system to get on it. The existing engine had an electric start with battery. Which charging system do I get? 16amp alternator, 3/5 amp duel amp alternator,..
