I have used one of those Gunson Colortunes in the past on a car engine. It was OK to see if the mixture was rich but not so easy to tell if it was lean. You almost need to adjust the mixture so that it is rich and then gradually lean it until the flame turns blue so you know roughly where you are with the mixture.

Hm, interestig. I checked today plugs again and every looks similar and good. I don't belive that something bad is with engine. I discovered that I have swapped 1 and 3 sensor (MAG/PTO side) or right, affected side. This weekend I'll try to exchange this sensors to check if it's sensor problem.

OK, I inspected today sensors. One (with low temp) looks like this:





Not good. So probably I found the problem. I have to look for K-type egt's in good price.

This does happen from time to time (not real common). It may be a little more prevalent when high EGT's are present for long periods.
