Moin Leutz I’ve been having a big problem with my Hyosung sb 50 cab for almost a week. he just doesn’t want to start. I’ve already checked everything cylinder, piston, membrane, carburetor, luff, and and and just not the engine block but otherwise everything resealed and scratched… the box gets spirt and a spark of ignition is also there only after some time kick gets the one misignition and skin behind out of the exhaust a small flame out… .. mass kaben I got, ignite coil have I also changed, and anner cdi checks the cables and also bought a new spark plug…. the only thing I can still imagine is that the light marchie might spin or the magnet switch that the cdi says where the ot is……I hope you can help me thanks imm vorraus 🙂 Speedguru HELP
