You dont really have to, i took it easy on the first tank of my HPI, I leaned it out about 1/4 turn and let her rip!!! Always run a good synthetic oil, my first tank i ran a good plain 2 stroke 2nd tank on i used synthetic.
I run techniplate synthetic at 25 to 1 ratio. For break in I just took it real easy on it. After about half way through the second tank, I started to open it up a bit. By the third tank the engine really responded well and runs great.
