    Thanks guys. All good tips to check out this week. I had pulled the plugs. They didn’t show signs of water but I’ll check again next time it’s run. It idles nice and at slow speeds purrs where a bad water jacket would be more throughout all speeds. I will check compression. If all above seem ok then I’ll get to tearing down the carbs and good point not mix the positions up.
