...it might just be an alignment issue. As the extrude wanted to push the filiment down, and the retract would pull it out just fine. Any other thoughts? It is hard to tell but could I just tighten the hobbed bolt more to get it to move in further?

Something's not right there. Duh. Comparing to my printer, your bearing does appear to be fully seated, and the left side of my guidler rides against the extruder body just like yours is. If you take things apart, you could see if the hole for the bearing needs to be cleaned out some, and you could try a thinner washer under the head of the hobbed bolt. I doubt that'd fix the misalignment you have though. Have you tried talking to Colin about it, perhaps sending him the picture or linking to here? Maybe they end up with a bad hobbed bolt every now and then.

EDIT: And looking at my printer for this I now see the kapton tape I had wrapped around the hobbed bolt to improve the fit in the bearings has crept into the cut area of the hobbed bolt for some reason. I wonder how long ago that happened.
