here my scooter Rex Rs 400 50ccm he has 4444 km down. When I got him last time he didn’t pull any more correctly than I gave gas he drove, but only 20-30 kmh when I gave more gas he bagged off and drove 5 kmh no idea what that’s about… carburetor is new cdi is new Battery is also good in shot as far as I can judge. I wanted to start him again over the kickstarter but had to fix that this was worn on the grooves and I got him so Cannot start
