[Healeys] SU Carb tuning

[Awgertoo at aol.com]

I too had always been under the impression that lifting the pin  on a 
particular carb gave an indication on its--versus its partner's--state of  
richness/leanness until quite recently a very smart and experienced mechanic  friend 
said it was just the opposite and explained why as this string bears  out.  Volvo 
and Healey SU's are both the same in fucntion--and one  would think that the 
Brits could explain in better and more accurate  English the operation and 
tuning of an English carb than could the  Swedes, but who knows!  
 
In any case as Alan points out this only has to do with idle settings and  I 
think we are more concerned with mixture at mid to high rpm ranges  depending 
on how we use our cars.  I still prefer to run the car at a  particular speed, 
then shut it down and read the plugs--NGK in my case--as they  do not lie.
