Thanks Sean,

But I'm in a little of a conundrum since to get the engine to pass the vertical test, I have to run it half turn richer. If I lean it out too much, I'm afraid that I will have to practice my deadstick landings frequently! Can I lean out the low needle and not have to worry about it as long as I can pass the vertical test on full throttle?

By the way, Sean, can you explain to me why the pinch test works? It is because it essentially leans out your mixture and thus the slight blip in RPM? A slight blip means that you are running just slightly rich, right?
