My outboard is running rough with poor acceleration and occasional stall and the fumes coming from the motor appear to be very strong. I'm new to this so not sure what's normal. The problem seems to getting worse each time I use the boat. Its getting harder to start. I just bought the boat and it seemed ok the first time I took it out. I've had it out about 4 times. It also seems harder to start when the moter is warm. My gut tells me that too much oil is getting mixed with the gas and the plugs are getting fouled. But that's only a guess. Thanks
