I've just started one of the sea doo's after I winterized it last year and it's smoking pretty heavily. Last year I sprayed fogging oil into the carb until the sea doo smoked pretty heavily. I then took out the spark plugs, sprayed fogging oil in them then turned the engine over a few times. So, my question is, how long should the billowing white smoke take to burn off? The ski's are 2002 Sea Doo GTI LE's with the 717 rotax engines. Thanks
