If it cranks, it's not the kill switch. Mine died in the rain once at Pat's last year. Started up and was fine, but I was only a mile from his place. I would suggest some sort of "pre filter" for under that filter. I think I remember someone else doing this. Like a sotchbrite pad, or a sponge, or piece of foam, or like some of that foam padding for carpets, or something. Something so the water won't liuterally flow inside. OR if you can get to an autoparts place, see if you can buy one of those filter condoms for a K&N pod filter. Maybe cut it into a flat piece, or just slip it over the end of the filter and slider her in.
