so I was wondering how you adjust the mixture precisely on the RV-6? There's no EGT or fuel flow gauge (to my knowledge), and the mixture doesn't seem to affect the RPM much. so my only guess seems to be by sound.But what if your playing on low volume.....seems like there should be a gauge to judge the mixture by?

I use the digitial RPM gauge. . .

for me the RPM stays constant with the mixture anywhere from 17%-100%......I don't have auto mixture on either. So the rpm doesn't start to drop until mixture is under 17%..

There's another long thread on this already, which may have additional information.Hook
