Good afternoon guys! Hopefully you've got some good information for me!My Dad has a 1971 Farmall 544 gasser (gear drive). It had been running poorly at the end of last fall and he decided to have the carburetor gone through by the local CNH boys. Upon their disassembly, they found the plastic venturi was cracked and missing a piece. Upon rebuilding it, the tractor does run a heck of a lot better...but I am having quite a time getting things adjusted now that it has been reinstalled. I have tried setting the carb as described by the 544 operators manual...close the idle adjusting needle screw to it's seat and back it out one turn, start the engine and warm the engine. It seems to run well at full throttle, but after I return it to idle, the engine surges. You can actually see the governor linkage running back and forth as the engine rises and falls. The idle adjusting needle screw will do nothing to alleviate this. I can turn the screw in or out till it falls on it's face, but the whole time it will continue to surge. Also once it is warm, I can only speed up the engine by moving the throttle open slowly. If I just open it up, it will almost immediately die. Maybe the winter has just been too much for this poor guys brain! Should I be looking into the governor? Thanks in advance guys! You are always a big help! Billy
