Years ago, when I was a wee young MC racer, we used to use a carb cleaner that was fantastic. The stuff was a syrupy brown liquid with a wonderful odor (at least I liked it). It came in a can with a parts basket in it. All you had to do was disassemble a carb, put the pieces in the basket, put the basket in the goo and leave it overnight. The next day all the carb parts would be so clean they looked new. Every bit of varnish and crud was gone yet everything was dimensionally perfect. I have been told that that product is off the market for health and environmental reasons.<br /><br />Is there anything nearly as good today? I am going to rebuild some OB carbs and would like to get them really clean and shiny. What products do you use to clean carbs nowadays?<br /><br />oneoldude
