I have a 50hp ELPTO Merc (ser# 0t082174) I have had this motor for a few years and it has ran great. I haven't had to do any maint besides plugs and impellers. For some reason, it is getting cold natured. Even after it is warm I have to choke it and get on the throttle pretty quick, or sometimes it will die. In gear it idles about 700 rpms, but sometimes it idles rough and will die. It runs great when I get some rpms. I always run marine stabil and have checked my fuel lines for deterioration, everything looks good. I have also noticed fuel/oil ON my carbs and down my airbox. I am not sure if it pours out when I trim the motor up, or what. I have sprayed carb cleaner through the carbs, but it didn't help. Anyone seen this before?
