Walt! So you can see when you're burning 4.2 gph instead of maybe 4.0. Car gas ain't cheap ya know. What's funny is the mixture screws are located UNDER each carb. You have to remove them both to make any changes (trial and error of course), put em back on, take em back off...etc.
Not a stupid question. Another question is why do you need a $225 fuel flow meter. Mine broke so I turned it off ....ahhh the beauty of glass cockpits.
