Is the Van’s Series CHT gauge actually a practical way to lean?
As I understand the temp range between Best Economy and Max Power is only 15deg or so.
The Van’s gauge is graduated by x100deg.
Wouldn’t you need a magnifying glass to lean properly?
Is anyone using the Van’s Series CHT gauge to lean?
For now - this is only for a flight simulator.
Using another gauge is an option, but the Van's gauge is already in place.
It's just not as helpful as I hoped. Isn't it meant for leaning?

My plane just uses cylinder #3 for the Vans CHT & EGT gauges. Usually the #3 cylinder will run the hottest............but not all the time, as is known with setups that measure all cylinder temps.

Since I have a carb, I'm most likely running rich of peak, but can't say for sure in regards to all four cylinders. I use the lean to rough, and then enrichen method. What I do know, is that with the altitudes I usually fly (7500-10500') is that the EGT is the one I take notice of. It's around 1325 degrees when everything is running smoothly and leaned for altitude. If I see it in the 1100-1200 range, I'll lean some more. If I don't, I can count on fowled plugs during the next mag check.

Gauges can also show different readings on different airplanes, just due to the location of the temperature probe in the exhaust pipe.
