Try partial and full choke and see if it runs any better, if it does its lean. That could be from a dirty carb or wrong jets. If it runs even worse its rich which could be again a dirty carb, miss adjusted float or wrong jetting. another thing to check is for vacuum leaks around the carb and head. With the engine running spray some carb cleaner or starting fluid around the carb mount on the head side and carb side and listen for rpm changes. If you notice the rpm change then its sucking air in which will cause all kinds of issues.

Do you have a voltmeter? they will go a long way in helping you chase electrical issues.
