I have a 1930 Case Model CO that has some problems--the clutch is stuck[engaged] and I can't seem to get oil up to the rocker arms. The little oil pressure button moves out when I start the engine but no oil makes it way up to the valve train. Any ideas?
Thanks in advance.

The clutches on these tractor will stick a lot if left in the egaged position.
I have had good luck by removing the side cover then use a brass drift and a large hammer to tap the clutch pressue plate while holding pressure on the release lever. Just don't get carried away and hit it to hard. The large hammer is best so you can get a good bounce with little effort. The drift should be about 1 in. or larger to transfer the shock from the hammer. It shouldn't take to much to get it to pop loose. Walt

Remove the clutch housing side covers and soak the clutch assembly down with some P.B. Blaster. After it has soaked for as few days, reach into the housing with a pry bar and pull on the hand cluch leaver at the same time. Be careful not to apply too much pressure.

C series tractors did not get oil to the valves and rocker arms. Operator manual says to remove cover and oil daily during heavy use. Some have manufactured their own ways of oiling the rockers. I am going to drill a hole in the cover of my C and put an oil/grease cup with a copper tube to each side for oiling. Might have to split the tractor to solve the problem with the clutch. Check through the side covers. Hope this helps.

If your going to go to the trouble of dilling and mounting a grease cup, you may consider a Rube Goldberg device with 4 access points in the cover. Mount an oil reservoir and oiler pump from an old fashioned chain saw like a David Bradely on the dash, or within close reach to pump it every once in a while so you get occasional oil lubrication to the rockers rather than grease.
