Mower leaks fuel from carburator when shut down. I put a shutoff valve before the filter to temporarily solve problem 3 years ago. I,m guessing that its from that solenoid but its hard for me to see down there. Is that solenoid really necessary? Or should I buy a solenoid and orings? Does a new carb come with a solenoid. Help Good Info I can use None from I heard from a guy please Jim Senn Athol Idaho
