Well tonight I installed the smaller bore center pin, to see if it will stop the leak. I went to refill and there was more leaking than I had ever seen before, I figured it was worth a try. I gotta say that this is a really tight draw. I am not sure this is going to work for me, this is just a bit too tight. I ended up taking out the plastic screw to see if it would open it up a bit, but it did not make too much difference. I will try it for a while and see about the leaking, but I will most likely go back to the original center pin.

Edit: Okay scratch that, I ran about a 1/4 tank threw it, and it was just not enjoyable. There was no point in trying it any longer, much to tight for me, and I like a tight draw.
