hey guys, got a question about my nova N12LLT3 motor...

ever since when it was new when you tightened the flywheel onto the crankshaft there is a little front to back movement through the little bearing in front of the flywheel. everythings tight it just looks like it rocks on the inner race a little and seems very strange.

is this normal for nova motors? as i have never expirienced this before with any other motor brand i have bought before and this is my first nova motor so i cant guage it against any others.
