I have an analog EGT setup, made by Westerburg, sold by Pegasus. My probes
are in the #1 and #4 pipes, about 6" away from the face of the head, per
manufacturer's instructions. Kas has since pointed out that a better
location is cylinders 2 AND 3.
Let me repeat what I said in the previous message -- I saw 1650 when the
mixture was TOO LEAN. I don't see it when it's right. The lean condition
occurred when I switched from Stromberg carbs to SU's without modifying the
jets in the SU's, and again when the pressure regulator went on the fritz.
Finding stuff like that is my primary reason for using an EGT gauge. I
haven't been able to correlate EGT's with optimum mixtures, but they are
useful in determining balance.
