I have a 1976 kz750b and I have had a common problem between my original BS38 and parts carburetors. My starter body slides have seemed to be seized from the aluminum oxidation from the starter body itself. Is there any methods of removing the slide such as a chemical soak or heating it? I would like to reuse the slide also as I haven’t been able to find any for sell. I would very much appreciate help as it has held up my entire restoration project.
