[Mgs] MGA sputtering engine

[Paul Hunt]

Any rotor can break down of course, but the ones that seem to be most prone 
have a domed rivet inside the circle of the base of the rotor, whereas the 
originals have a flat rivet outside.  Other types with a domed rivet outside 
the base circle are also OK, see http://www.mgb-stuff.org.uk/rotors.htm. 
Burning though may be invisible as it is internal, but is detectable with a 
timing light if by clipping it onto the coil lead and cranking it flashes, 
but it doesn't on any of the plug leads.  Incidentally if it flashes on some 
coil leads but not others, then it is the cap that is breaking down.
