Yes. I would also recommend a higher percentage of nitro. Get yourself some 25% and start the break in process again (you won't have to do so many tanks this time though, don't worry), return to factory settings, run one tank at idle. If it doesn't get very hot (over 200 needed), then lean it a bit and repeat the process. After the first tank which reaches 200+ let it cool (with the piston at BDC) and then start it up again. this time put it on the ground and run around at medium throttle, again looking to get the temps up over 200. After 3 or 4 tanks of this, you can start tuning. It won't take long.
