Engine MCGHS - Won't turn over

[haydad]

Ran the mower for 3 hours all went well. Shut it off and the next day opened the "lid", lifted the seat, and sprayed all the leaves off the engine with a hose. Let it dry. Several hours later went to start the engine all that happened is a metallic click sound. Sounded like the starter was trying to kick in but all that was heard was a click sound. According to the owner, it was they sound they hear when the battery is to low to turn the engine over. Put a battery charger on the unit for 24 hours and no improvement. Removed the battery a week later, cells are full, and the voltage is 12.32 V, battery was new in 2013. Mower does not get a lot of use.

Any thoughts as to how to get the engine to turn over, or fix the metallic click sound.

Thank you.

First remove the spark plug and serif you can rotate it by hand.
Then try doing it with the starter.

Was able to perform the task suggested. When the key was turned on, the same click noise was heard.

The battery was taken to an auto store and it checked "good" but needed to be charged. It was charged before the test requested was done.

Other thoughts?

Thanks
