Point setting on a Case 300 tractor?

To set the ignition points on a Case 300 tractor, first, ensure the engine is off and cool. Remove the distributor cap to access the points, then rotate the engine until the points are fully open. Use a feeler gauge to measure the gap, which should typically be set to 0.020 inches; adjust the points as necessary. Finally, reassemble the components and double-check the gap before starting the engine.
