CG will not effect the stall other than increase (nose heavy) or decrease (less nose heavy) the speed at which it stalls. How it stalls is controlled by wing design and pilot inputs.
Edit: this was not directed at you Speed I forgot to hit the reply button.
A CG that is too far forward will make the plane behave like it is heavier than what it really is.
The OP should take note of his elevator trim for level flight after he lands it. If he has a bunch of UP elevator dialed in, he needs to shift the weight aft.
