Couple things here.. first off, voltage alone isn’t a sure indication of battery power. Are you reading that 12.3V open-circuit, or when it’s connected to the starter during the test? If you connect a 12V car headlight, does it burn nice & bright for a few minutes without fading? Load-testing is the way to go.
Also, if the starter was +just+ serviced, it may be that the brushes aren’t properly seated yet. After verifying your battery condition is A-OK, try the test again, but give the starter case a good hard smack with a hunk of 2×4 or bang it on the benchtop and see if it takes off. You can also try rotating the armature a few degrees to a different segment / brush contact position (don’t do that when the battery is connected).
