Actually I ended up coating the metal welds with JB Weld because of pinhole air leaks when I pressure tested it. But I finally got it airtight. So the welding job may appear better than it is. :BigGrin: Shiny paint covers a multitude of sins...
So far so good. I put it on an engine in my bike that needs other work before I can road test it. You can see a video of it running under my topics titled "It runs".
