My two cents. Having had lots of carb issues over the years. When you take them apart, especially with the description you gave. The carb is still slightly clogged. If it was mine I would pull it back apart, disassemble, remove all of the parts and the acces plugs (aluminum) get a light and a piece of piano wire and make sure they are clear. Once you route them out, spray with carb cleaner and then blow them out. (dont forget about the ball bearing)
