TOO MUCH SMOKE AT IDLE

[Jack retired]

This is all new to me..........I just bought my first Jet Boat a 1999 Sugar Sand Tango. It smokes too much at idle but after idle and all day running high RPMs it runs just fine with little to no smoke. Pull into the dock and I'm killing more than just mosquitos. Any help is much appreciated.

Sounds like a carb adjustment. Does it run rough at idle and slow speed?

runs just fine, is there info on adjustments ?

There is a sugar & sand section on this forum. I'm sure someone has an owners or repair manual to help you out. You will find it under Model Specific Discussions.

Older tired 2 strokes seep oil from the sump side to the combustion side when left to sit for some time. Could never get rid of it on my seadoo 717 engine. At least it helped control mosquitoes
