So yesterday I was just finishing up rebuilding my K301 fro m 125. So with the extra freetime I thought I'd tear into my 1450 to see why it smokes so much. I had bought a head gasket in advance just in case that was the case. I opened it up to see this and my heart sank.

Is this fixable?
It seems like such a big oval that it may not be recoverable.
I also have some questions about my newly rebuilt K301.
It has spark and everything but it is really hard to turn over on the compression stroke.
How do I overcome this? Do I just need to wear it in? I have a normal Lawn and garden battery to jump it. I have tried a car battery that probably needed to be charged and that wasn't much better. What should I do to get it started? Is there some kind of compression release?
