Bought a jug of EvapoRust at Advance Auto Parts Tuesday, first time user.
I soaked a pair of upper and lower Zenith carb castings in it last nite, came out GREAT. I had wire brushed the heavy crud off beforehand. Bought some plastic storage food containers at Dollar General, three for a buck, to let them soak in. Rinsed them off with water, blew out the chambers with compressed air (they are all clean now) and painted the castings with three coats of fuel proof gloss black paint. Looks great
This stuff doesn't affect the brass plugs or float hinge attachment. Put a dab of Vaseline on the brass plugs to keep the paint off. No need to drill them out to clean the passages.
I'm sold on the stuff great product.
Got some Renner's flowed jets ordered I'm sitting pretty
