Linda and Dave, Dave is on to something there.
I noted the same phenomenon a while back and wrote a similar comment into the ercoupe.org FAQ. The Stromberg carb reacts slowly but with good accuracy. I found that I could do 10° control of the temperature with an accurate EGT gauge. I could easily control whether I was at peak, 50° rich of peak or 100° rich of peak or whatever. But I had to move my standard push-pull very slowly and carefully but I could do it. I thought about installing a vernier mixture control but never got around to doing so. The standard push-pull is adequate but *I* think it's important to have a high accuracy EGT gauge with 10° marks or a digital readout. Ed
