To my knowledge, black is probably the most effective color for =
radiating heat. Not all, but the vast majority of electronic heat sinks =
are now finished with black anodizing.
A very THIN layer of black paint is a GOOD thing. Too much and what you =
end up with is an insulating blanket. Most radiator shops use a thin =
paint with just enough solids to turn the surface black. If there are =
several layers of black paint, it can become a factor.
More typically, radiator efficiency is lost through a lot of rust and =
scale inside the radiator.
I think John's suggestion about checking the water distribution tube is =
a good one.
As I mentioned before, you should check your timing and make sure the =
advance is working properly.
Have fun,
Alan

The radiator shop did paint my radiator black when they repaired it and
boiled it. What is the recommended method for removing paint from the
radiator?
