I need to identify the carbs. on my 94' 40Hp HSMS .According to my Selco manual I should have Tekki or Nikki carbs. but I have Keihin's on mine. They are fairly large and square where as the others look small and are roundish in shape.None of the pics. in the book jive with what I have. They are factory. The markings on mine are "6H4OB HHO3". I may need to go into them and clean them soon,not sure yet,but I don't have the correct specs. to do it.What gives and what do I have?
