The carb of my 1998 30 horse Johnson BJ30BAECS is leaking fuel from the air intake area. A repair manual says that the emulsion tube could leak and tells almost everything I need to know to test it, but not enough. As seen in attachment here of the text about the leak issue, a syringe is to be filled with alcohol and the idle circuit is to be filled with the alcohol with the carb inverted and any leaks seen then repaired with a sealer. But it doesn't say where the idle circuit is, and exactly where to inject the alcohol. The typical carb in the books illustration is very close to my carb which is pictured next to the book's text about the emulsion tube, so the testing instructions should apply to my carb. Might anyone know the exact location of where the alcohol is injected in the carb, and where the idle passage circuit is in this style carb?
