Working on a carb from 1988 evinrude yachtwin 4hp that needs the 1.6 mm brass tube that run through the throat of the carb into the high speed nozzle. The center portion is missing. From what I read it only comes with the carb body. Does anyone have a cut a way of that carb that shows if there are any small holes in the center portion that point either front or rear of the carb. The enclosed photo is what I have . I've obtained 1.6 mm brass tube to make a new one. Any help would be appreciated. Thanks
