I'm new to the site and have a problem with my 96 Seadoo GTI that has never been fixed. When I start it up it puts out a TON of white smoke. I had it in the shop a few years ago. They rebuilt the carb, flushed the gas tank and replaced something to do with the exhaust. I haven't used it in a year and started it yesterday. It put out so much smoke (in 10 seconds) that it looked like something was on fire on our street. Also spat out a lot of oil from the exhaust. Normal? Any advice? Thanks.
