Running Rough

Ran great before putting away last season. It has been sitting for a while. I had to replace the battery also. It will start and stay running while I have the choke on but once I turn off the choke it cuts off. It doesn't sound right at low rpm's. I took it for a quick ride and it has plenty of power when I go down the road, but once I grab the clutch while slowing down for a stop sign it turns off. My gas tank is about or a little less than half full.

Could it just be condensation in the gas tank? Anyone have any ideas?

Thanks,

I'd .....
check/change plugs .
Get some good gas in there .
Throw some Seafoam in there .
If that don't do it , then you'll probably wanna search for the how-to on carb cleaning ....
