running too rich can cause high EGT's. Not necessarily knock, but almost all the symptoms of it.

You might want to get o2 voltages. EGT's is a guide to a good air/fuel gauge. Both lean and rich can cause high EGT's but how high or how low? You NEED an air/fuel gauge that reads o2 volts to use the EGT to it full potential.

Go to www.armond30.com and look under the technical info. Near the bottom Armond wrote a short essay on what causes knock.
