Lynn,
I presume this only works with a carburetor ??.............
That is probably the case.

One tuning trick for racers is to get on a long straight at full tilt and shut off the fuel pumps. If the power drops off instantly it was too lean. If the power goes up a bit and then goes away, it was right on mixture. (just rich of peak EGT).
This would be too lean also for long apex seal life. If it builds power for a second or longer then goes flat, it was a bit too rich. Kind of crude but it works, and tells you where you are with no equipment at all. The idle circuit is all by itself.
