[Healeys] solid state pump

Years ago, I bought a kit from SU to convert a points-type pump to solid 
state.  The conversion steps were fairly complex and the kit came with a 
'special' forked spacer to set the gap properly. I think it would be 
problematic to (re-)set the gap, esp. without this tool.  FWIW, after 
following the steps carefully the converted pump only worked a few 
hundred miles before dying.

Some have had good luck with points, but I would only get a few thousand 
miles on a set, and the aftermarket points I've seen in the last few 
years appear to be of poor quality.   I've had some success with Dave 
DuBois repairs/conversions, with one going over 30K miles, but one 
failed me recently in the CA/NV desert after only a few hundred miles.  
Still, with all their faults, I can't bring myself to give up on the SUs.
