I would be very skeptical of the use of carburetor cleaner on plastic. When cleaning carburetors with it, the first precaution is to disassemble the carb and make sure none of the plastic parts go into the solution. Scale Coat rinse away is very effective, but Atlas and Kato shells can be damaged by it. I don't know for sure about Bachmann. You would need to test on the inside of the shell to be sure. If you don't want to scrub, you might look into an ultra sound parts washer from Micro Mark.
