I have a Johnson model 243 updraft carb I'm rebuilding. It came apart easily, I found rebuild instructions and new float etc. I would like to clean the body of the carb. Make it look shiny. Any suggestions?
Is it a brass carb? If so, I like to lightly grit blast them, or LIGHTLY wire wheel them, then "polish" them using brass polish and a toothbrush. It doesn't get it to shine brightly, but makes it look like a new casting. Wire wheeling to make a bright finish does not look good to my eye.
Jerry it is brass, yes
A good alternative is brass case cleaner liquid, its available from any gunshop, its used to clean fired cases before reloading. Works like a charm and doesn't etch the brass. I believe the main component is phosforic acid.
I use glass beads, gives them a nice soft glow.
Ok yes this a link to my ad on ebay but I included before and after photos;
