While fishing in July my 115 Yamaha wouldn’t go above around 3000rpms but ran fine otherwise. I have had this problem on and off since I bought 4 years ago yada yada yada. So I bought the service manual and 2 carb rebuild kits and cleaned he carbs. I took it out twice this week and is running great.
When disassembling the carbs I found the pilot screws set at 1.5 turns out. According to my service manual the screws should be set at 5/8 turn out. When I put the carbs back on I kept the settings they were at. I have always thought my motor ran pretty smokey I just figured at least it was getting lubed. But now I’m wondering if it is because of the pilot screw settings and I’m wondering if I should change the settings to the factory setting. The motor is idling where it should be and runs pretty well. I don’t have a ton of experience with 2 strokes anybody have any opinions on this?
