Got my set of new orings to clean up the carbs on my 84 GS450t in the mail and tore into them earlier today. Everything came apart easy enough and the inside of the carbs where covered in a fine tan colored powdery substance, no goo at all. The carb slide seems to be stuck in the down position and after a little coaxing with a screwdriver and trying to pry it upward it doesn't want to move. Shot it with some carb cleaner and needless to say with the diaphragm still in place I'm hesitant to just drop it into the carb dip. A couple of websites suggest heating the carb body with a propane torch, soaking it in marvel mystery oil, tranny fluid, invoking the spirits of aincient Greek goddesses... you get the idea. I'm thinking that boiling in plain water is safest on the diaphragm but if anyone here has a better idea, I'd appreciate the input.
