I recently got tired of dealing with the mechanical fuel pump on my Marine L654 and bought the Kohler kit to convert it.. it seems to work great but I can’t get the ratio right on the air/fuel and it’s running rich. The normal carb adjustments in the manual seem to only be good for the mechanical pump. Can anyone advise on leaning this thing out a little? I have the autochoke turned to the lean side but haven’t done much adjusting on the carb.. It’s tough to stand on the swim platform because it’s so rich.
