I have a 9.9 4 stroke yamaha from day 1 this motor has smoked for 10-15 seconds on a cold start. dealer has adj. carb. and it still smokes if I let it sit for 5-6 hrs.By smoking Imean a big cloud of smoke.After it stops,motor seems to run fine.Could be because the rings didn"t seat right? Thanks Does anyone have email for yamaha motor corp.?
