Adjusting the carburetor

McCormick Farmall and International 460 – 560

per the Preventative Maintenance Manual dated 6-20-58

"The engine and carburetor are correctly set when shipped from the factory...Start the engine and allow it to operate until thoroughly warm before making any adjustments.

... with the engine thoroughly warm, turn off. Close the [top needle] idle adjusting screw to its seat; then open one turn. The [bottom adj. screw] main fuel adjusting screw can be used to reduce the amount of fuel going into the engine when under light load conditions. However, when heavy work is to be performed in which the FULL POWER of the engine IS REQUIRED, the fuel adjusting screw should be set five turns off its seat. With the engine running at fast idle, turn in the throttle stop screw a few turns to prevent the engine from stopping when the throttle is closed. Start engine, close the throttle by pushing the engine speed control lever all the way up. [I like the way they worded that.] The throttle stop screw can be backed out until the desired idle speed (approximately 425 r.p.m.) is obtained. If the engine misses or rolls, the idle adjusting screw may be adjusted either in or out until the engine operates smoothly.

Hope this helps.
