Hmmm...ran rich for 4-6 hours...not my idea of a good break-in for this engine...or for longevity...buy a new one and get a three year warranty.
TT PRO .46's need to be broken in HOT...one click shy of full lean for two minutes with a 9x6 prop, then go to a 11x5 and run it through 3-4 tanks at full throttle a couple of clicks lean past the rich/lean break setting. It will just keep getting better after that.
After any running ALWAYS use an after-run oil. I will typically fill the carb venturi with oil and then work it into the engine. Then let it flow to the head and then drain off the excess through the muffler.
Engines treated in this manner run flawlessly and seem to last forever.
