I have a 2001 22 HP Intek with 800 hours and it just started the following symptoms. My battery is fully charged and is only a coupla years old. When I go to start it cold (summer 60+ degrees) it just clicks and the flywheel does not spin. I keep turning the key off and on and it starts turning over slowly, off and on, until after about a minute of messing with the key, it finally starts spinning properly and it starts. When I shut it off hot, it starts right up. Whats going on?
