Grind/Growl Troubleshoot assistance

[Alpha D]

Old Thread Resurrection BUMP....This problem ended up being my old starter teeth that seemed to be not worn abnormally or anything however they didnt like the fly wheel ring gear. So i swapped in a new starter as last resort before pulling the transmission and it fixed the noise. As some know i ended up having bigger problems ha! My question however...Is that the norm for a starter and a new flywheel not to mesh up so well...? Granted all is aligned?
