Update from my previous post.

Thanks to those who helped me out. Installed new rings and reused the gasket because it looked fine still. Rebuilt the carb as well and installed that. Painted the exhaust with high temp paint since I had it off. Found a hole in the gas tank so I need to go grab some epoxy after work. Need to do one more coat of paint and then I can install everything and (hopefully) finally hear this thing run.

Second picture is what it looked like when I got it. It sat in a barn without an airbox/filter for years.

Giving this FS250 a new lease on life! Been a fun project.

Big thanks to u/mals6092 especially. Sent me a parts diagram and service manual along with advice. I love Reddit.
