My brother came to me excited about sandblasting his carb because a friend of his is about to do the same to his.
I told him that sandblasting a carb is a bad idea because the small idle ports and such will be effected by the sandblasting, vitually making the carb useless.

 

I wouldn't do it. Theoratically you can blow out all the passages afterward to clear out any sand, but you never know if one is gonna get stuck somewhere and be a total PITA to trace down.

 

yeah..i wouldnt do it either....now sandblasting an intake manifold is different.......

 

I tried sandblasting an old 600 holley I had, but was not using. I taped off the front and back with duct tape to prevent the sand from entering the passages.

 

At my school they had a bucket of this carb cleaner stuff. I took the carb apart, removed all plastic and rubber, and left it in the chemical for a day. It came out looking like new
