Hey I have an old set of carbs, that dosen't. look good. But they work just fine. They are a temp fix, I've don't have the funds to fix my Dell'orto's, so these are gonna stay on for some time now. But I want to clean them of on the outside. They are dirty and has that white/dusty look of coroded carbs. In Denmark we don't have carb cleaner, and I dont want to buy a sonic cleaner. Same lack of funds the won't allow me to rebuild my Dell'orto's.
