Check water temperature in the top tank with a meat thermometer.My JD has a radiator shutter to control water temp.The farmall H has got to have a thermostat in it.Chances are you will find it missing or stuck open.My John Deere will not show any heat on the temp gauge unlees I am mowing in thick grass.Running an engine without a thermostat is done often,its plain stupid to do this.My John Deere was designed to run with out a water pump or thermostat.I adjust the radiator shutter to bring the temp up.Check your heat range on the spark plugs and suspect poor gas also.Remember that the engine runs on the idle circuit at low rpm.
