I am doing a project and was researching some information and found this site and read some information as to what I am doing but it didn't have all the answers needed. I'm doing a project on egt readings and twin cylinder 2 stroke snowmobile engines. For example what effects higher or lower readings. Would an increase in the air mixture, enough to create a lean meltdown on the intake side of the piston would EGT readings show this. Would an increase in the fuel mixture actually cool things off, would this show in EGT readings. Would EGT readings drop or raise if DETO was happening in one of those cylinders. Would readings drop because the piston and wall are absorbing all the extra heat. If someone could explain some of these to me it would be very appreciated.
