I have a 86 115Hp motor that bogs down at take off and has lost top end and is hard to get going after it sets for like 30 min. I have read that adjusting the idle mixture screws from the bottom carb to the top is a good place to start and need to do this on the water. I like to work on my own stuff before I take in to the shop and spend $$$. My question is which screw is the Mix screw on the carb. I tried to pump the prime bulb while running and it does nothing. I have been looking for a picture on the screw to turn out but have not seen one. I rebuilt the carbs a couple years ago and have not had any problems since then. I do run stable and sea foam during the year and my bowels are clean. The motor sounds like it has kicked into another gear after it is at 40MPH when WOT but only speeds up to around 43. It use to do 57 at WOT on my 156 Stratos. Thanks for any info.
