Rebuild, follow the e50 tutorials in the wiki, the Sachs is different but the basic premise is the same
Be careful not to damage the washers and shims on the crank.
Replace the bearings and seals.
Also maybe 1st, be sure its not something easier like something wrong in the clutch, or possibly a coil on the ignition rubbing the flywheel
It has a safety switch the taillight has a return to the magneto it's usually blue or blue black it has low watt hard to find 2w and 3w taillights or may have a resistor block. If it's not right it won't start also the taillight ground return wire and magneto return out grounded to frame and have a redundant. and frame to engine ground it has rubber mounts. If it turns over when you try starting it the pivot pin in the clutch can be tighter slightly if it is worn a little.
