I've done a few carbs with sand and never achieved a smooth finish like you have. Same with glass bead, it was too harsh.

Nissanman Member March 26, 200717 yr comment_13154 Share this post A blow out with clean compressed air is the only after treatment. This is all that the Mikuni Solex Manual advises for cleaning their carbs. but I don't think they had grit blasting in mind when they wrote that:surprised I have always wanted to try glass bead media but can't seem to find any available in Oz. Another thread talks of Baking Soda as a medium. If I can find a bulk supplier I may try that out. Doing it outside the cabinet is a filthy exercise but sometimes it is necessary e.g. the air plenum on my '73 Z was blasted out, inside my garage. Freakin' grit got EVERYWHERE:mad: But, how else to remove the rusty bits?? After I had finished, I swept the floor and put it in a storage bucket, to be used again...
