Great job. People tilt the model vertically to check for a sagging engine. Any engine sag lets you know there's an over lean condition.

Ahhh, so in my case I was running rich so holding it vertical didnt really prove anything. I want to try that when I have the engine running lean and see if it will stay strong when held vertical. I'll also try the throttle test.
I also see that if you pinch the fuel line " it should NOT speed up" before it dies?




Thanks
