MEK works wonders!!! you could buy it at a paint supply store!!!VERY DANGEROUS TO HANDLE,,but,,works well!! (methyl ethyl ketones). I'm going to do a post about sucking AUTOMATIC trans fluid through your fuel system for storage throughout the summertime.. It keeps EVERYTHING as FRESH AS A DAISY, fogging your whole motor and cleaning your powervalves ALL SUMMER LONG!!! You will NEVER have to take your carbs apart for cleaning again!!! Also, I will talk about SACRIFICIAL ANODES (fitch) and the molecular structure of todays "oxygenated SUPER FUELS".. For simple carb cleaning I use HOGWASH and for VARNISHED UP SOLID carbs that have been sitting with fuel in them for many years,, i prefer MEK!!! Gary Oles nosboy
