: "I have been running this Briggs & Stratton motor on my push mower for over three seasons. It handles thick, overgrown grass without bogging down. If it ever struggles to fire up after a cold winter, a quick carb clean or a fresh spark plug immediately restores it to a first-pull start. It is an absolute workhorse for standard yard maintenance." Option 2: Hustler Engine Plate Repair Kit (Part 121682) 121682
