I have a 98 Yamaha 115 2 stroke that I bought used. It seemed to be running rich because of what I thought was excessive smoke. I read up on adjusting the pilot screw and according to my manual, it says that all four should be anywhere from 3/8 of a turn to 7/8. When I checked what they were currently at, they were at 1 1/2 turns which according to the manual would be extremely rich. So I picked the middle of the recommended settings and set them at 5/8 of a turn. Helped with the smoke for sure. Seems to run well at higher speed but I think the idle was kind of rough so I turned them to 3/4 of a turn. With that setting, I don't notice a big difference.
Also, it definitely runs different on the muffs than in the water. I would like to make the adjustments while I'm on the water but I've found I need to take off the air baffle to get at them.
Is there a post somewhere that will detail how to dial in those settings?
Thanks
