So life happens. My poor M750 sat untouched for the past 2 years. I am now gettig her back up and running. Tried turning the throttle and it was basically stuck. The carbs are so caked with laquer from the fuel, that the flapper disks (whatever they are called), are almost stuck closed. I got a rebuild kit on order since the bowl gaskets are pretty hard. I also have a gallon of acetone standing by. My main question is, how far do I need to take the carb apart before it is safe to soak in acetone? How long do I soak it? I am told the acetone will eat rubber, so I would think every gasket and o-ring would need to be removed first? What about the brass jets?
This is my first time rebuilding a carb, so bear with me. If there are any in depth how to's that go into immense detail, please let me know where, as all of the search tools and google have failed me thus far. I have included a picture of the carbs with the bowls removed, for your viewing pleasure.
