I will try that. I have a second carb for it already because of this idea. This tractor has many more hours than most and has plenty of wear. The weird part is I will sit and run high at any rpm it just can't be reved quick or put under any load

Another thing that might of happened as it happened to me is something vibrated loose.

Wire connection somewhere, these engines shake a lot and in my case the ground wire came loose.

Caused erratic running.

 

It's not black smoking or stalling right out, I still say something loose, electrical, shorts out or breaks connection as vibration changes.

I've look but can't find any loose wires. Any key places to check? And you cannot see it in vid but it will smoke slightly.
Any idea on what the squeak you can hear is??

The Squeak ???

 

Maybe head gasket leaking, the head bolts tight?

Or maybe gasket itself n/g. ???

Once again I will check but see no reason the shouldn't be. The engine haven't been apart in 25 years

You could remove the cylinder head while the engines still hot and check your theory of the exhaust valve binding in the engine block. I think if it were me I would check to see what  my timing was doing with a timing light before I disassembled anything. Only takes a second. I would expect to see a steady flash nothing erratic.

had the same problem with my mf 14.  tryed every thing to repair. exhaust valve was sticking only when hot and with some load.  Changed oil and put some transmission oil in. ran it for a while then changed oil again.  put oil and transmission oil in again.  works great now. Noel 

P. s.  found fix on internet, someone else was having same problem.
