Glad you resurected this old machine. 1)Adjust the governor rod 2)You should have a a minimum of 15 psi at 400 rpm idling speed. Since you have 25-30 psi at high idle(2200 rpm),I"d say your mains were OK. I suspect your relief valve may be stuck partly open causing low idle oil pressure so low. 3)If the lift arm won"t go down, your lift piston may be stuck or binding in the lift cylinder or your control valve may be stuck. What"s the fluid look like? This is another area where condensation causes water to get into the trans/hydraulic fluid and can cause sludge to form that"s not good for the hydraulic system. Jeff(OH) has a proceedure for cleaning the trans/hydraulic system that you can find with an archives search.
4) This is common. Make sure that you have a FAT, BLUISH-WHITE SPARK, and then adjust the small needle on the throat portion of the carb. Remember it controls the idle air so enrichment occurs when you screw it inwards. 5) Check a salvage yard or ebay for the broken part. 6) You know what to do about these items. You might want to consider cleaning up the fuel tank. These old machine that sit out for years have fuel tanks full of crap and corruption that eventually start causing problems with fuel delivery. Many have broken tank baffles that stir up this junk when you drive the tractor and it becomes a full time job trying to maintain adequate fuel delivery. Welcome to the world of Ferguson Tractors!
