Default OS Engines .32 Heli

If the engine is old it may need a new piston and sleeve. I have had a couple engines go on me and they run like they are rich with little power but they are hot. If the piston and sleeve are still good you may have an air leak. Air leaks can make an engine run very oddly. If there are no leaks then it just needs to be re-tuned. Put the settings from the manual back into it and adjust it from there. I say this because if one setting is too far off it will affect the engine temp and the other needle setting. For instance if the low end is too lean and the high end is too rich it will run hot unless you keep it at high throttle but will seem rich all around.
