Carburetor Rebuild
I am rebuilding a carburetor for a 1976 Corvette. I have a brand new cabinet that I plan on dedicating for media blasting for carburetor and internal engine parts.
Has anyone used walnut shells for cleaning a dismantled carburetor? Any recomendations for the equipment or standard blast cabinet will be fine?
I have read about soda blasting. I understand that if you don't have the right equipment it can clump. Does this happenw with walnut shells?
Thanks

SOda probably clumps if you do not run a drier.

I'm not so sure that you want to blast carb parts. They do have plating on them, so I'm not sure if removing that plating is a concern, or not. I've always just soaked carb parts in carb cleaner and blown the residue off (and out of the passages). Also, blasting could cause media to lodge in those passages.

If you blast the carb, you'll be removing all the plating on the die cast zinc parts. This will make the carb porous, and it can actually leak through the casting: The plating on the carb is a sealer, so if you remove it, you better find someone who can actually re-do all the original style plating/sealant...
I generally regard blasted carbs to be destroyed and not suitable for rebuild or service.

I had no idea. Good thing I ask before I blast!
