There may be a bit of grit caught in the float valve, holding it open. Or, the float has after all these years just gotten out of adjustment.

Over the years, this has happened to me occasionally, on a number of different machines. If it is a bit of grit, launch it off some big jumps and land hard, and that will usually jar the float enough to dislodge it.

If not, you will have to take the carb off. Might as well do a thorough cleaning, and then check the float adjustment.
