You will likely get a lot of different advice from a lot of different people. I just don't see how they would know more about how to treat the engine than the engineers that designed and built it. I would do what those instructions say.

OS .46 FX
If it indeed is an FX rest assured you have in your hands one of the finest engines every produced bar none. If its LA, no comment.
(a little secret if its an FX, after its been run awhile, you dont have to run higher nitro, but if you want to give it a treat, load in some 15% and it will run like a scalded fox!)

Good Start
Some has guided you correctly! You've been really paying attention! I was going to get a .70 FS and put it in Hanger-9 .40 size Cessna, would have been a perfect match, was going to buy it the next day.
But however, I took off with the ailerons reversed :stupid: It was a sad day, but life goes on ......

I start the motor in a rich mode for one tank of fuel always checking the temp. Second tank is run from rich to almost lean always checking the head temp. When lean it gets hot and you richen it up till it cools down then back up. Third tank is almost lean out and you just control the rpm up till it gets hot and back down till it cools off. Fourth tank your needle is set and you stay at high rpm for about 1/3 tank and then start checking your setting from low rpm to high, by this time you mid range needle will need to be reset. about 1/16 to 1/8 of a turn will set you for you first flite. I have my motors in the airplanes when I do my run in this way I can now check the plane out and see if I forgot to make everything tight and if everything goes the right way with the controls anyway have fun let ls know how you do...

FX46
FX46 is one of my favorite engines, next to the 61FX that is in my SeaFury! Of course the 32SX is also a really sweet engine in my sons LT25! It has the power of the FX40, uses less fuel and is a lot quieter! Come to think of it, I like all my OS engines!
