OK, my outboard is giving me fits again. It is my fault for letting it sit between uses like I have while building the house and trying to get everything else on the house done, only getting used once in a great while. It runs fine in the driveway, and on the ramp, and will idle fine. Problem is as soon as you put it under load, it just bogs and dies. Last time out though I did notice this. If I hold my hand over the intake of the carb, limiting the airflow, it runs like a stirped a#* ape! Does this sound like an air fuel mixture problem? I have messed with the screw for that, until I am blue in the face, with not much success. It is almost easier to hold my hand over the intake. It is a mid 80's ( I think 86) Mercury 25hp tiller. I have used seafoam and stabil in the fuel, but I did start it with some dirty fuel in the beginning of the year, I know, I am a stupid a##! :embarassed: Any advise will be appreciated!
