What to say, my mower Doesn't start, just clicks when turning the key. I installed a new solenoid valve and it worked like new again. The nuts weren't the same size as the OEM solenoid and it's not as thick or heavy as the original part so time will tell how it holds up. use. If lifespan is short I will update my review, if there is no update it still works and I will continue to recommend this part if you watch pennies.
