Norm - how did you prep all those small carb parts?

In a 5lb vibratory tumbler with green diamond shaped media and a little degreaser. I have a sandblast cabinet but it’s almost impossible to blast small parts. Once they come out of the tumbler, I rinse and dry them. They then get dipped in metal prep for a few minutes before a distilled water rinse and into the zinc. I use POR15 metal prep however I believe it to be just a mild sulfurique or muriatic acid. It’s just convenient to buy pre-mixed and it’s reusable. For the tumbler, forget about the HF unit, go to Eastwood, if you figure out the price of the media at HF you’ll find they cost the same and Eastwood is a better unit. You can also get extra bowls for $20 to use separate media and not need to clean the bowl every time you switch.
