I replaced the spark plugs with some hotter ones. I went with Champion W16Y I bought on
After taking it for a spin, I still had bad overheating problems. I pulled the radiator to swap the spare I have that is in better shape. I am going to take it to a radiator shop to make sure its completely clean before installing it. There was a thick brown sludge that came out of the one I removed.
"New" is on the right.
