It’s been forty years since I’ve run a HD, but doesn’t it have exhaust relief holes about half way down? Water should spray out those (if it does have ’em). One thing about a HD, if it overheats, the fuel will boil in the carburetor and it won’t run worth a hoot.
A common HD cooling problem is the water tube enters the pump via a chunk of rubber. Those things often moosh over at the end of the tube, restricting the flow. Just carve it away if it does.
