The FD620D Kawasaki 22hp engine in my JD 445 lawn tractor is having issues. My crankcase was leaking antifreeze from the top and the engine was overheating, so I took it all apart, replaced the water pump with a new one, used form-a-gasket for the crankcase, and put it all back together. Changed the oil, put 15W40 in with a new filter, and I started it and it ran for a couple minutes on low power, but it sounded whiny and wouldn't run on the lowest power, it lacked batter power and would quit. As I cranked the engine speed up after a couple minutes, I heard somewhat of a popping sound and instinct was to turn the tractor off. I tried to turn it back on and it wouldn't start. It turned over, but no starting. Did I break a gear inside the crankcase by chance? Is there some sensor thats telling the engine not to fire or could it just be spark/fuel/air issue? I can rule out the air issue, and I was about to take the spark plugs out to check them, and I can smell fuel.
Why won't it start??
