Have you adjusted the valves and cleaned the carb?  What engine is on the Motobravo?  2T? 4T? 50cc? 150cc?  1500cc? Wink

How many miles on this scooter? 

Work the kick lever a few times slowly with your hand and feel for compression. If it has good compression it will fight you and then it will get easy and then it will fight you after the engine rotates around again.
