EGT/CHT Probe Location

Captain Ron

Les Cedres, QC, Canada
Hey folks,

I just bought a EGT/CHT gauge and I was wondering what cylinder the probes should be installed on. The instructions say the leanest (hottest)and my gut tells me that is cylinder number 3 (and hey, that's the one that swallowed the exhaust valve before...). Any suggestions or advice?


I have a EI CHT/EGT and put it on the left rear cylinder. EGT probe 1.5" down from the exhaust flange per manufactures instructions.
