Re: Temperature Balancing by Turning/Twisting the Carb

Great work on the intake elbows. I thought the change would be greater. My left rear EGT is the hottest/leanest on climb out, but something I have noticed is that when that cylinder is getting hot, if I retard the throttle a small amount that cylinder will cool without a noticeable change in rpm. I thinking the throttle slide is not linear. At the wot position it goes lean and a small amount of change in slide position eliminates it. Just an unsupported observation.
From what I'm told by Bill Larson, the turbo is the best homogenizer for even temps. And, we all know that a warm/hot intake manifold runs better than a cold one. Lycoming design? Have you seen ice form on the manifold above the Aeroinjector? I'm thinking that more heat applied to the intake manifold wound increase atomization, reducing the heavy particles at the intake elbow. Ducting the top oil cooler over the pipes may be a simpler approach. Just saying.
