So thats the very front of the block huh? I was expecting to see it from the side for some reason...
The side plugs I believe, are further from the liners than the front plug is.
What happen, you just starting smacking it thinking it must move quite abit, but instead, it was up against the liner almost instantly, but you didn't think it was, so you figured I'll get that sucker to move... one way or another...lol
Please don't get mad... I'm just picking at you. I can definitely see myself doing that...
