Well more confused than normal. Last time i used the MH 333 I had coolant coming out the radiator over flow and temp got up to around 210. Figured thermostat. Had a little fun locating thermosat and gasket. Thermostat got from Napa and gasket from Wayne Steinhardt in Canada. Pulled it apart this morning and found no thermostat in the tractor. Well I had everything, so once I figured out how the replacement thrmostat went, put it back together and fired her up with the radiator cap off. Got operating temp and thermostat open. Ran for about 10 minutes everything working good, put cap on and still working good. Not sure why temp straighten out with a thermostat in it. Seen to remember being told years ago that an engine ran cooler with a thermostat than without. :?

You need to slow the water down to have proper heat transfer.
If the water is going to fast is dont have time to remove any heat, slow it down and control it your good!!!!!

That makes a lot of sense.
Thanks

I was talking to a old timer who used to race Flathead Fords on some type of short dirt track and it was common practise to replace thermostates with plain washers and expierment with what diameter of hole worked best for a certain temperature
