pining,twin plugging,etc...

[Bruce Plecan]

Which brings up an interesting point, when improving
ignition systems, sometimes you wind up running less
timing.  Which means there is a better flame/reaction
or it's burning faster initially?.  But, would that be a 
indication of a better VE?.  According to some the ideal
plug gap would be .1", which would min the delay of the
flame getting to be a large enough kernel to burn quickly
though out the combustion chamber.
 Bruce   Safety alert:  don't try and dry your foil lined 
              Cone Shaped Hats in a microwave. (specially
              if there are traces of gasoline on it).
