A few questions; How long is "a few months"? Same old gas in the tank? How long was the ride "down the street"? 15 minutes or less? I'd drop the carb bowl on the offending side and check for any water, debris or a plugged vent tube (that skinny tube in the float bowl) you should be able to see through it. Also let some gas flow through the carb while lifting and dropping the float, to flush out anything that might be making the float needle stick. Then, like the others have said, adjust the valves, set the timing etc before attempting to adjust the carbs.
