When brake is taken off, motor stops

[Kenbo]

I have a simplicity 24 HP Zero turn. Last week I turned it over and most of it got wet. I let it sit and dry out and that evening it started fine except for a little blue smoke and used it several times the next day. 5 days later, I started it and it ran fine. When I took the brake off to move it, it stopped. I tried it several times and the same thing happens.

What do you mean when you say "I turned it over and most of it got wet." I'm not sure I understand what you are saying.

Dry out all the safety switches you may have got water in one of them, the blue smoke was oil burning when you tip it up.
