If your oil pressure gage is stock the needle should be on the 'O','R', or 'M' with the engine at normal operating temperature. This equals 6, 9, or 12 psi respectively. Be sure the metal tube sticking up from the oil filter mount is in place. They will occasionally come out and get tossed away with a filter. If your oil pressure gage is an after market gage it be about a 20 psi max reading gage.

You may raise the oil pressure some by restricting the oil flow thru that sorry excuse for an oil filter.....!!!!

Check the book , but I think there is a nut, about 1" size, on the right side of the engine near the steering shaft, with washers behind, that can adjust oil pressure.

Yes, it is something like that. Remember though that you only want 10 to 15 tops psi though. It is the only large nut on the side of the block that doesn't hold something on, really a plug with a hex head.

Yes, thats right the oil press. regulator spring cap is on the right side of the block near the bottom. Large capscrew plug...can't miss it. You can either replace the worn spring or shim it. Also don't forget to check that the plunger behind the spring can easily travel in the bore.
