I've checked the MSDS sheets for a few of the over the counter carb cleaners and also found several home brew recipes for carb cleaner. Many of them contain Acetone, MEK, Xylene and some other fairly strong solvents. I'm a little hesitant to soak the carbs in those formulations for fear that the solvents will attack the plastic. What can be used that will give good results? Granted gasoline is a pretty strong solvent and it doesn't affect the carbs, but I just want to know if there are any solvents that should be avoided.
