Mix and knead (and knead, and knead, not briefly), rest, and sprinkle with a little more flour if the dough is too sticky to pass through the rollers.
If you have a scale, weighing the ingredients may help. I don't use salt or oil in my noodles; just whole eggs and flour in a 2 to 3 egg to flour ratio. For example, crack 3 eggs into a bowl and weigh them. Let's say they weigh 180 grams. Scramble them lightly with a fork and add them to 270 grams "00" flour. 2:3::180:270. Mix and knead (and knead, and knead, not briefly), rest, and sprinkle with a little more flour if the dough is too sticky to pass through the rollers. Don't give up!
