Hello how are you, I hope I can explain it , I understand very little English. the question is :what fuel oil ratio should I use in my outboard motor? I have tested with 50:1 but a lot of smoke and i need to know where is my problem? I read that there is 100:1 ratio but need to be sure not to cause damage to the engine, I look forward solution as I have not found anything regarding this engine model. thank i hope your answer soon.
