I did the ones on my 1998 90hp Yamaha on my Hewes. I had no choice wouldn't run at high speed. Being lazy or a bit stupid, I did not disconnect the fuel line and run the gas out of the carbs everytime before I would let it sit for long periods of time. Anyway it was a piece of cake, not like other American carbs I've worked on, it's all sealed with O-rings and was very easy to clean and re-assemble. I just soaked the metal items ovenight in a gallon of carb cleaner bought at the local auto parts store. The problem was a stuck "needle and seat", used an old tooth brush and Qtips, careful cleaning and then put everything back like it was. No problems in the last four years. And I do run the gas out every time now to finish my freshwater flushing.
