Likely a stuck carburetor float. You can try to open it up using Gumout carb cleaner - open the drain screw on one carb, shoot some Gumout up into the carb (using the "straw" that came with the container) until you see the cleaner coming out of the top of the carb, pull the straw out and put that drain screw back in and tighten it down. Let it sit for a couple of hours. Repeat on the other carb. That may not be enough to loosen whatever's causing the float to stick, but it sometimes works and is a lot easier than a carb pull! Good luck.

Welcome to the boards Dave, you posted this question in the right forum. So now come and introduce yourself on the newbie checkin forum, so we can get to know you a bit. Go to the user cp and fill out your profile and sig line too. You might be close enough to another member to be riding or wrenching buddies.
Enjoy the ride.

I had this problem too, managed to avoid a carb removal. After doing the gumout through drain trick above, I added a fair bit o' Seafoam to my tank, ran it for a minute to get the solvent-laden gas into the carbs, shut it off. Every 15 minutes for the next few hours (I was working outside) I hammered on the carbs with a screwdriver handle, then ran it for a minute. Eventually, the combination of tricks loosened it up to where it would run reasonably well, then an easy ride finished clearing it out. Good luck!
