Glad you got it cooling properly. 🙂
I was waiting for someone else to post this possible cause of overheating 3 hp’s , but I guess he’s busy at the moment . 😉
He had an issue with a JW where a tiny pebble was lodged in the bend at the top of the water tube. He could blow compressed air through it so he thought it was clear, but not enough water would make it past and the little JW would overheat. Had him stymied for a while. 😛
