I got that TTR to turn over today with a borrowed battery, but it's still not starting so I'll probably take the carb out and clean it when I have the time. Initially, when I turned the gas on, it would drain straight out of what looks like an overflow tube. I hear that is a sign that the floats might be stuck. I rapped a bit on the carb with a screwdriver handle and it stopped leaking. Replaced the plug even though it looked fine. Oil level is normal and looks brand new. I guess I'll have to actually go through it instead of hoping it'd start right up.
