Don't use a cutting bit. Sand by fingers in the direction of flow. The above mentioned flap wheel would be good if you could get it to the correct angle. Once it is fairly smooth you're good. Super smooth, and not polished, is for speed tuning only and would not be noticed in normal use. Get the bearings and seals out, toss them, then do so very serious cleaning. At the bottom of the left side transfer port there looks like a small round depression. If that is filled with the crankcase casting, that's fine. If it is a hole filled with shavings, seriously clean it. About the crack in the reed valve area; if the crankcase sealing surfaces are good, then the 'crack won't hurt anything if there are no small cracks coming from it.

Thanks for the input. I just started and was just trying to get the major divots smooth. I was maybe thinking of taking the Tig welder at my work and at a low voltage using that to smooth everything out and then using a fine sandpaper to finish it with?

Looks a lot better than it did. This should be fine. Unless you're going for some hyper race, super speed deal, this will be just fine. But... You will probably want to rip it open again later, when you're more experienced, and try again....hahaha..personal experience.
