So far, so good! I did replace the drive disc, which made it 100x nicer to drive/ride! It took a bit of patience to get it set correctly, but it works nicely now. I think I screwed the carb up a bit though. I had the fuel cap vent closed to tilt it up and work on it, and forgot to open it again. It was running like crap, and I figured maybe a piece of trash ended up in the carb, and started playing with the settings. Then I had the epiphany...the vent was closed! Doph!!! It still runs, but if I idle it down, it wants to shut off. If I find the carb settings on the net, I'll try to reset it. Not a big deal at this point!
