Excessive white smoke?

[nitrix]

Hi, I recently rebuilt my Suzuki ZZ 50cc after it sat for about 16 months. I Replaced the piston, rings, bearing, gaskets etc, cleaned the carb, I got it started today and it's blowing lots of pure white smoke?
I know 2 strokes do blow some white smoke but this is A LOT of smoke. anyone know what the problem might be?

Well white smoke from an engine is generally water. How long has it been sat? Could you have got water in the fuel?

I cleaned the tank too, but the smoking problem has practically gone after a few good runs, strange, thanks anyway

2Ts smoke when cold and all will have white vapor from condensation
