I recently picked this up for almost nothing, close to brand new condition but it wouldn't run. I rebuilt the carb with an oem zama kit, and now it will start kind of, but won't run. I can keep it running longer id I keep it choked or half choked, but I still cant use it. I'm mostly familiar with chainsaw carbs, this one is different. Has a barrel with a cylinder inside with and opening that turns when I hit the throttle. Any guess where to go from here?
