I am looking for some guidance on increasing the idle a little on my Johnson 130. It is currently idling very low so much so that when I put it in gear it will die. If I put it in gear quick and idle up fast boat performs fine. I just need it bumped a little on the rpm when in neutral. I cannot find anything online as to what screw to adjust. There are some many on the linkage and then there is a idle timing screw and WOT timing screw that I don't want to touch. If anyone has experinence with this or a picture of which screw I can adjust to bump idle a little it would be much appreciated. Thanks so much!
