Got this recently. A 35 Yamaha 2 stroke with oil injection. IT sat for a few years at least, but is in like new condition. It started but smoked for 10 minutes until it cleared up. It was on a stand all that time and when we moved it, it started leaking. IT runs funny as when the throttle is increased it balks and will not rev up far and is rough. Should I clean the carbs or is it something related to the oil do you think?
