Carb Cleaning

1430 Views 9 Replies 7 Participants Last post by  ROSKO
I have some carbs that have been left a long time and have this dark brown stuff, which is a hard varnish like gunge in them. What is the best way of getting rid of the stuff. Is is in the float chambers, on the floats, in jets, in the carb throats etc.
I was going to try ultrasonic cleaning in acetone, but acetone does not seem to shift the stuff.

Hello again,

I strip the carbs into parts and clean individual parts- so you don't need a large cleaner. I think the sort that you see in Harbor Freight would be OK if the tank is about 4 or 5 inches square and same depth.

Engine case cleaning - straight in the dishwasher in the depth of night seems as good as anything - just don't get caught otherwise you loose your dangly things in a painful manner.
