The local ford tractor guru says I am nuts for putting a stat in my 2N, The problem is that he patches and pedals and I plan on working the heck out of mine, so I took all of you guys advice and I am going to put one in. I found a stat for a Mercury after going through Oreillys parts books. It is 192 degree, but I think I will drill a quarter inch hole in it for bypass and bleeding air, what do you all think is this a good idea or should I go with an eighth inch hole as usual? Another stat that will work in our tractors I believe is out of a Renault, but that was a special order from O'reillys.
