Here is a better picture of the pistons. I have them connected by the wrist pin. It does not free port.

I did not do anything to the muffler yet but a gasket match.

The exhaust side of the cylinder
I just did a gasket match to it.
Before

No After picture, I forgot to take one.
The intake side
I just cleaned it up a little.
Before (really bad picture)

After
Could I have opened the left side up to match the right side?

I have it running. I used it just a little this afternoon. I had to put a 20" bar and chain on it because I don't have a 16" chain yet. I want to run it a little bit then I might do a muffler mod. Thanks for the help.
