I was not able to get the 45 that I got in a plane swap to start a few days ago, but I was running with a carb that sat for 3 years out of use and I did not have a muffler. I found an old OS muffler in my vast collection of mufflers and am in the process of carving out an adapter for it. However, I kept thinking that the engine felt quite heavy for its size. That is especially since Fox engines typically tend to be lightweight for their displacement. Then I realized why. The engine backplate is filled with what looks like melted lead. Maybe a previous owner needed weight on the nose of the plane? How do I get that stuff out?
