The high speed performance too is exceptionally good. We consider this magneto is generally arranged fundamentally correctly and we do not think the magneto has been "nursed" to obtain the extraordinary good results. The general workmanship and design appears robust and reliable and the whole magneto should put up a reliably good performance in service. The other magneto No 99802 is also being similarly tested.
