I bought my TEA 20 six years ago not exactly what I was buying other than a small to mid size tractor. I stumble upon this forum and have been reading for several years of and on. My Fergie finally needed an overhaul and I have found that parts for the TEA's are sometimes hard to locate. I even had to send to England to get brake shoe liners several years ago and now I can no longer find that site back. Anyway in overhauling the engine I have found that it did not have a thermostat in place and I would like to know if anyone can tell me what or where to get a thermostat. It is the Standard 85 engine. Thanks
