I think I have found the problem with my engine, but not sure how to fix it. The front brass piece (with the double orings and touches the red bolt) seems to be sitting about 1mm from the black can. When i push forward, the leak stops, but i obviously can't do that while playing. How is the brass front piece attached to the front black can?
hmmm it just looks like it need to be pushed in, but maybe the can is just a hair too short?
I know I had some issues using the poppet's back cap screws in the new engine. They just did not want to go in. It was like whoever tapped the threads never cleaned them up, so that's what I essentially had to do.
