I bought a used Cub Cadet CC30H, it starts and runs well for about 20 minutes, then it misfires and dies. I have fresh fuel, new fuel & air filter, new spark plug and oil/filter change.
After about 10 minutes it starts and does the same again. I don't hear a hiss after it dies and I loosen the fuel cap so doubt that's plugged. When I replaced the fuel filter I did install a paper element filter vs a red screen type, could that be a cause.
