I was not trying to reprimand the OP. But if you want a good answer you have to give good information. If you will notice there are no more generator techs on this site.They all got tired of trying to help. When people would not list proper information. So we all left.
Now as for his question. Pure acetone should never be used to soak carbs. It can and does attack some metals.Forget to remove any plastic parts and they will be gone. The ideas of using an additive. Is just trying some save time and labor.
I have cleaned many carbs by using some cleaner in a can of gas.Most of the time it works fine.But sometimes the carb needs to be soaked in a carb solution. Then blown out with air.
