Engine is hard to start in the rain...

[lukecp]

I have a 350 in my truck, with a edelbrock 1406 carb, and a 14x3 open element air cleaner sitting on the stock air cleaner spacer above the carb. My problem is, that whenever i drive it for a little while in the rain, it has a hard time starting back up. I will have to crank the motor over about 5 times as long as usual, and it dosen't want to idle just after you get it started. I'm guessing this is because it is getting water sucked into the air cleaner. I THINK that it isn't water in the distriubtor because it didn't do this with the stock air cleaner, and the engine proably wouldn't run at all with water in there. So, is this a problem that i just have to live with, or is there any way that i can keep water out of there?
