Once you get it on tight, whack the end of the puller with a hammer (as if you are using the center bolt as a punch to push the crankshaft end out the other side of the flywheel). Usually a few times is all it takes for the flywheel to pop off. If it does not come off with 3-4 whacks, retighten the center bolt and try again.
