have you measured the mag plate bush diameter against a known crank thickness,,get a set of dividers or similar take a reading off the crank,, get some small wooden dowel and reduce in a drill and sand paper so thy are the same dia,,,,there should be virtually nil radial play,,, at 3/4 to full revs if there is radial play the end of the crank actalluy vibrates and interferes with the spark and stutters the engine,,,,or measure a new bush against the old one fitted in the stator,,,,also if it has an earlier lumpy cam fitted that limmeted the rpm a bit compared to the smooth lift later cams from d5 onwards,,,,,,,check the strength of the points spring against another set if its weak this could also give the fault,,, is it the long type of silencer,,,the short ones dont seem to rev as high
