If the throttle shaft is moving, unlikely it is the governor.

Re: 420C right steering clutch slippage.
Often times it is oil contamination, which tends to get worse as the clutch gets warmer.

Re: Oops?
Make sure that the throttle shaft is not iced up in the carburetor, not uncommon in cold weather.

Re: jd420 pics
If you put the head gasket in dry, that is often an issue. Use one of the copper sprays, or Hylomar.

Re: What gas for an old 420c?
You can add a little lead substitute if you want. You likely aren't going to put on enough hours to cause much valve recession. Octane is a waste of time on these old girls, probably 7 to 1 compression maybe.

Re: JD 440IC Steering Clutch Adjustment
If at 1 1/2" the throwout just begins to move outward, it is an adjustment issue with the connecting rod between the steering lever shaft and the throwout quill. If the adjusting bolt is at the bottom of the slot (farthest away from the pressure plate), then yes, the discs are shot. Unless you addre...

Re: JD 440IC Steering Clutch Adjustment
Maybe I am missing something, but none of the measurements you state seem correct to me. Steering levers should be back 1 5/8" give or take to set the throwout bearing. Reread the manual carefully, it is likely just an adjustment error.

Re: 440 back firing
Timing can not jump on these barring a mechanical failure of some sort. It is likelly an ignition issue, possible faulty piece, etc. Check the timing with a trouble light, then you know for sure on timing. Check all connections, check polarity on coil and anything else you can think of. Then for kic...

Re: Cracked housing repair
They are cast iron, vee it out, braze it and run it. There is no concentrated stress on the hole, it is distributed around the hole by the bearing quill. It is likely a crack from prior in it's life when a bearing went out and played nutcracker with the gears, and cracked the case. Normally it just ...

Re: Grease in Rockshaft
I can't see it hurting anything, but better make sure it is full, and coming out past the seals or you won't have any grease around the shaft.
