Are there rich/lean screws on my carbs. I think my outboard is running to rich, the reason I think that is I have fuel trail running down my mid section like it's coming out the case breather? And a fuel trail coming out of the prop where the exhaust comes out. I'm premixed 50 to 1. Seems like it's gets flooded on start up but runs fine when cruising around. Are there factory adjustments cause I can't find anything? Any help would be great.
