Ryan,


I believe you engine has a water cooling head, which cold water running through it, impelled by the prop.

I believe that even with an air-cooled engine, the remotely measured temperature is not only inaccurate, but also only remotely related to the average temperature of the cylinder head's internal surface...
It also very dependent on the exact point, to which you aim your thermometer...

Engines ran and lasted long before the first remote model engine thermometer was invented.

Adjusting a model engine is done using your ears. The engine will audibly "tell" you if it is running very rich and cold, rich, just fine, lean, or very lean and hot. You must only learn to identify your engine's sound.

Using a remote thermometer is redundant and it will not help you, if you cannot identify the sounds without it.


Because of the cooling jacket that encapsulates your engine's head, any number that anyone gives you here, will be meaningless.
