I have an FG14 in a H9 Pulse 60 and it is super reliable and with unbelievable fuel economy. I can't tune out a persistent miss at anything above idle, everyone keeps saying it sounds rich, but it doesn't seem to affect the reliability or power too much. If I lean it a few more clicks, it still misses but risks quiting. I'll keep flying as it seems to get better as I fly more. I suspect I'll need at least 4  hours on the engine before I can expect perfect tuning.
