Moin, had changed the partial load needle settings with my scooter due to start problems, which ended in that the partial load needle was not properly inside due to my inability. However, the scooter then started (only with startspray), but immediately ran full throttle without calming down (because of the partial load needle). Had run the approx. 2 min on full throttle and nothing happened. Did the needle now properly inside and now the scooter does not start at all. The spark plug is dry Since it already ran it can not actually lie on the carburettor or? or should I just clean it. Lg
