Cub Cadet with Kawasaki FH721v Engine Won't StartI have a 2008 Cub Cadet with a Kawasaki FH 721v 25 hp engine and it will not start. I have replaced the coil packs, spark plugs, fuel filter, and fuel lines. I cleaned and rebuilt the carb, replaced the air filter, and fuel back fire solenoid. It will run briefly after starter fluid is added or gas is added directly to the carb. I know the fuel pump is working.
