Need some help with setting up the governor on a Miller big 40 with a Continental motor. The motor is a 4 cylinder flat head F163 with a gear driven governor. The only numbers I see on the governor are F600S and below that is 4540. I have no manuals on the governor.I am rebuilding the tired motor and would like to set this up correctly. So if anyone can point me in the right direction would be greatly appreciated.
