    I've noticed that every time i either hose off the mower or get caught in the rain the engine won't start back up or either stalls. (19hp kawi on a scag tiger cub) Any ideas on whats going on here? Also this happens if i barely get the engine wet.

    No gaurantee, but I would blow off the spark plug wires and recesses with compressed air or blower. Works for me.

    You may want to check into this;
    Had a customer with the same engine and same problem, Every time he got caught in the rain it wouldn't start afterwords. I pulled the air filter and found water in the bottom of the air filter base, Blew it out and it cranked up. I put O-rings on the cover hold-down nuts and he hasn't complained since. Just make sure the O-rings fit the recess area on the nut and protrude enough to seal.

    When I have had this problem it was always a sing to me that the plug wires/boots were cracked. And it was not long until I would need a new coil.
