I have a 1949 Case Sc that used to run amazing I raked hay with it last year and 2nd cut I noticed I very slight change in the sound of the engine but it was really slight. So I kept raking after a few days it got so bad that it would barely run. So I replaced the intake manifold gaskets because they looked worn out and It didn?t change anything. I totally rebuilt the carburetor and it helped a little but not a whole lot. It runs okay at lower and mid throttle but when you give it higher rpm it?s surges. It runs high then idles way down then revs back up and it won?t stop. Is it the valves in the engine or a govener problem? Thanks for anything you might think.
