I don't have an O2 sensor. I richened up the Monojet as part of this tuneup(?). This is a used 292 I put in till I can another rebuilt. The intake and exhaust are off the 292 I had been running for several years. This is the first time I've ever held the RPMs up while watching the motor. I'm hoping it is normal for the headers to heat up cherry red like this. 4 and 5 do seem to redder that 2,3 or 6. The fan cools off 1,2,3, but 6. I don't know.
