If all you need is a good cleaning, then this is the place to send your carburetor. I don’t just spray or dip in the latest and greatest solution. I remove all factory plugs and expose all passages to a mechanical cleaning. Solutions are great for gum deposits and build up but they won’t touch corrosion, which is the major blocking agent in old carburetors that have been left outside, dormant for years. All rebuilds include cleaning.
