for lack of knowledge at the time last year i bought a cht, then found the EGT meter was better for getting temps to prevent a nip. Now I have fitted them both I was wondering if they can be used in anyway to find out correct carb jetting at different throttle settings or speeds?

Prabably one of the first things to do with it is to use it for jetting. Mark your throttle positions (1/8, 1/4, 1/2, 3/4 and full) and check your temperatures at all these positions together with plug colour. If your plug is the correct colour at, say 1/2 throttle, then make a note of the temperature at this point and apply this to all other throttle positions together with plug colour.
