RE: 25FX tuning problem?
Wow! You were asked at least twice if the engine was mounted inverted or not and still no answer, just a derogitory comment on how someone was born. Is it a secret about the engines orientation?
I have to agree with the "how many turns is it" response. What matters is if the engine runs where set. If inverted I would say hsn probably a little farther in than when upright. I always adjust my engines by sound, half turn out, 1 1/2, or 6 turns out, doesn't matter. Tune for maximum performance and then fly.
I understand you can be frustrated if it is not working right but from what I have read here you are just concerned about where the neddles are set rather that how it is running.
Good luck to you either way.
