I just got back from being over sea for the last 2 years. While I was gone, the bike was driven from time to time by a brother, though hasn't been started in 6 months. Of course the bike didn't start when I got home. The bike wasn't getting any gas, so I opened the carbs and found the float stuck. I cleaned everything out and put it back together. Now the bike starts except after idling for 20 seconds the pipe is bright red and starting to smoke as if it is going to melt. Plus gas is dripping out of the tubs on the carb. Though if I open the throttle, the dripping stops and the pipe burns up faster. Again I'm not idling longer than 30 second tops. I know that ilding these bikes are bad but I don't want to take off and ruin the bike if something really is wrong. I've looked it over again and again I'm not sure what I'm missing now. Some help would be nice.
