I was able to get my Mogul back from who I sold it to and I am glad I have it back. I never should have sold it. I was just running it and it ran great for about 10 minutes and then it just stoped and the piston valve on the left cylinder shot backwards out of the valve block. I am at a loss for why this happend or how to fix it. I can upload a pic. Any help would be greatly appreciated.
