there is no thermostat, didn't have one when i got it. it seems i am missing a part to reinstall the thermostat, i did buy a new thermostat just could not put it in.
A good amount of exhaust is directed through the water outlet at idle, so yes it should steam quite a bit. That outlet also functions as the exhaust idle relief.<br /><br />Are you missing the part under the thermostat? There should be a sleeve, spring and a little plunger for the spring.
