I find that the thermostat is a GOOD THING. It makes the engine warm up more quickly, reducing wear. It also helps against carberettor icing, which happens in the just-above-freezing-and-very-wet-air climate of western Washington winter. I never have had one stick open. I have heard people worry about it. I recommend that you hook it up, listen to your engine (you should anyway), and look at the thermo stat every tune up.
