I found this locally on craigslist a few days ago and picked it up today. I really wasn't looking for a new project, but many of us know how that goes! It's a 1971 XS1B. The engine is stuck and there weren't any other parts to go with it. I have since sprayed it liberally with Kroil Penetrating Fluid to hopefully free things up. The only challenging thing so far, is the right-hand spark plug has been broken off in the head and is flush with the top of the spark plug hole.
