Hello all! A while back I posted about some governor issues I was having with my '38 F20 - it seemed that there was no mid-range throttle, but only idle and then when advancing the throttle, you would get to a certain point and the engine would jump to 2/3 or full throttle. I tore it down some to inspect some parts, and it seems everything is moving freely, and does not seem to be hanging up on any shafts or assemblies. (Keep in mind I am working without a manual or exploded view diagram here)...
What I did notice is that the governor weights, on one side, had a cotter pin through each and a spring connection the two weights, so as to keep them in the closed position. The other side of the weights were drilled for the pins, but the spring and pins were missing. I replaced both springs and all cotter pins, and the tractor seems to be operating much better - but, it doesn't seem like I am getting a proper governor response under load. My question is - are these springs supposed to be there, or did someone add them at some point for some reason. Seems to me the weights should be able to move freely, only being regulated by the thrust bearing. Any ideas? I have included a video that shows the work I did (skip to about 24:40 in the video)... All help is appreciated!
