Singing In the Rain (Not!)
courtesy of Bob, The Auto Answer Man
I have a '85 Mazda RX7 with a 4-barrel carb. Lately, after it has rained hard, it will not start. When I finally get it to start (after eventually running down the battery and having to get a jump-start) a large amount of white vapor comes out the exhaust. My initial thought was that it might have a cracked distributor cap or deteriorated spark plug wire insulation, but that would not seem to explain the vapor. It seems as if moisture is somehow getting into the combustion chambers, but how? Yes, it does have an air filter on top of the carb. Any ideas?

Somehow water is getting into the fuel. There are two places your should make sure are in good order. The first is the carb. Check the air box to make sure that there are no leaks around it. The next is the gas tank. Make sure it is sealed. The most probable places for a leak in a gas tank are the gas cap, fuel filler neck entry to tank, and fuel level sending unit cover on top of the tank.
