Just bought this new project bike and got it to start and throttle up but it dies when I let off the throttle. After running the bike for a bit the left exhaust pipe was still cold and while the right was hot. Any ideas on what could be wrong?

Spark plug has a spark because when I removed the left spark plug cover the bike died right away.

Carb related. Floats could be stuck or out of spec. Or cleaning Like stated^

Could be simpler than that, for a while I struggled to route the fuel lines so that one of them would actually flow, the tight bends it has to take to get to the carb closer to the petcock can make it hard for the fuel to make it to the carb.

Also, make sure both spark plug leads were plugged in.

Where you located? I've been wanting a cb200T.
