How far out should the probes be mounted?  I've seen 2" and 6", does it
matter and, if so, what is optimal?   

BTW, although I didn't get my car back together in time for the Mitty, I
did have a great time watching and visiting with the other FOTers.
Thanks to all who put so much effort into it.   Don

You will find that the numbers 2 & 3 are always leaner than the other
cylinders if you are running just a pair of S.U.'s or Strombergs. Were
it me, these are the cylidners I'd have the probe in.
