Re: many problems i think
Spray carb cleaner or wd-40 around the engine while you have it idling to look for air leaks. You'll either hear the engine cut out or rev. Look around the carb or intake, as they are the most likely culprits.
Also most states require at least a drivers license to ride a MB. Although most police don't hassle riders.
