I was flying yesterday and it seemed that the engine started to loose power once I got it over half throttle. I thought it might be running too rich so I leaned it out a bit. I also changed the glow plug but that didn't change anything either. I looked into the tank and it doesn't seem like anything it clogging up the lines.

After keeping it on the ground and slowly bringing up the throttle the engine would die before it had enough lift to get it to hover. So what do you think? Was it way to rich for the weather conditions yesterday? I didn't have this problem before.

Thanks,
Mark

I had a very similar problem with my Ergo a few weeks ago. On the
recommendation from "avaition", who has been helping me told me to check all my fuel lines for any pin holes or just replace them all. Once I pulled the clunk line out of the tank I discovered it had gone gummy and soft. We believe that around half throttle the clunk line would colapse which then leaned out the engine extremely hence causing it to overheat thus losing power.
This was only after about half a gallon that the clunk line failed. Quite soon if you ask me.

This is what caused the problem with my engine. You could have a different problem but just an idea to check.

Sounds like it is too lean, like Dirt said. Try richening it up a few clicks at a time.

I'm no expert but this was happening to me on my os32sxh. The problem is there's just not any more fuel coming into the carb as you increase your throttle.

sounds lean to me aswell
yep lean it must be. if you still cant get it right try turning the needle all the way in then turn it 3 turns out(richen) again. this seems to be a standard place for most engines to be set at. then work it from that point
