Hi My 50 ccm scooter AGM GMX 450 6000Km throttled on mofa can only be started via kickstarter. At electric start it sounds like a heavy diesel trekker at the start and then goes anywhere or not. Battery,starter,carburettor, spark plug are new. Do I hit 2 – 3 times on the kickstarter he goes immediately. Driving is also not a problem when he is at once he runs. Sometimes he goes out at the ampel in standgas briefly. Can someone help me there? Thanks Stefan
