I agree with the objections to the thread starters instructions.
That stuff is old school.
Follow the damn manufacturs instructions. Good practice is heat cycling, and cooling with piston at BDC. Common is running rich, and running blips at full throttle.
You can't just give instructions to the whole RC community like the thread starter did.
Yeah, different engines require different breakins. I use this as a rule though: if the manufacturer says use 4 tanks to break in, I use 8. If the manufacturer says use 9 tanks, I use 13. Basically the 4 tanks after the manufacturers recommended break in, I would still run it easy and slow.
