Personally, i wouldn't be stripping the carb at this stage. It's possible that there may be some internal 'furring' as a result of the aluminium oxidising for sure and also that various seals, o-rings etc may have perished. However, that would have to be at quite an extreme level (unlikely) to cause the car not to start at all. The most likely cause of the car not starting is the ignition system. Either it being damp, or one or two vital components being kaput. The car needs air, fuel and spark to run. So once you've vouched that there is no water actually inside the engine in the way outlined above, those are the things to check. Air is easy, just make sure the air filter is clean. Fuel is also similarly easy to check (Assuming you've checked the car has fuel in the tank
). There are a few ways to check fuel. You could just turn the engine over and see if you can sniff petrol for a start. Pulling off the hose that supplies fuel to the fuel pressure regulator on the carb and sticking it in a glass whilst a friend turns the key would be another (more reliable) way. If fuel comes out into the glass, you have fuel. Spark is quite easy to check as well. Take a spark plug out, stick it's lead back on and rest it against the cylinder head. Get a mate to turn the key and you should see spark (don't touch the bugger though cos we are talking 20,000 volts or so!). If anyone of those checks doesn't pan out as it should, you have something to go on. There's obviously more possibilities, but that's what i'd be looking at first.
