I have farmall 400 that I just installed a 281 in place of the 264 that came with the tractor. When I start the engine it wants to pulsate from idle thru about half throttle. If I pull the choke out it smooths out and runs right. I have sprayed penetrating oil around the manifold and carb to see if I had a suction leak but didn"t find anything. I adjusted the pivot on the governor but that didn"t help either. The governor was originally on the 264 and worked good. The carb and manifold came with the 281. From half throttle on up it seems to run okay. Anyone have any ideas? Thanks Larry
