I went back over to the place today with a buddy of mine that wanted to look at the junk bikes and got lucky. I was digging around the tire pile and spotted the airbox and cover for the carb. Went on a major search, but couldn't find the carb or anything else. Did manage to find a cargo rack and side cover for my Spree though.
Once the spree is done, im going to tear into this guy. My dad may have a source for the carb and some other bits. Im going to tear the engine down for a full go over. Its been sitting for years, so it won't hurt to go through it all.
