Has anyone with a CHT gauge used a thermometer gun to check the accuracy of it? I was just pointing mine at the base of the spark plug on #3 and was only getting upper 200°. But it may have not been totally warmed up yet and it was just idling.

I would trust the CHT (if its a good one) before I trusted the IR gun.
There is not any good way to get the IR gun to measure the head where the ring terminal sits. Under #3 is the hottest part of the non-exhaust tract for the motor (in theory). So any other place you take a head temp reading (including on the top of the #3 plug) will be cooler - probably significantly cooler. Zach |
