Default OS 46 FX, no full throttle

My OS 46 FX, with new Enya 3 plug. I also tried other plugs. When it starts it dies if you give it full throttle either fast or slow, and with the glow igniter on or off. I have ran the needle out, in etc, and no change. Also if you run it at 1/3 throttle it will quit after about 30 seconds and the engine is hotter then normal. It doesn't matter if the needle is out 3 turns or 1. I have 5 OS engines, two of them are both OS 46FX. The other one is running great. But this one isn't. I inspected the sleeve and it appears to have normal up and down scratches, I don't notice any peeling. No scratch is deep enough to feel with your finger nail. They can only be seen with a magnifying glass. I have a GP Ultimate ready to fly and no motor, please help. This engine probably has had 50 flights on it and around 2 years old.

Thanks for any help.

Toy,
Assuming the engine used to run fine and the engine's low speed needle hasn't been played with by someone, the engine is in need of service. There may be some peeling, scoring, or other problems inside the engine, and each attempt to run it like this is likely taking her more and more lean and doing more and more damage.
