breaking in engine what % nitro to use
 

Hey guys I am going to break in my new nova rossi engine this weekend was wondering what percent fuel to use yes I did Google search and searched this form I have a size liters of sidewinder team fuel but it's 30% hoping that will be okay also should I touch the fact tory needle setting some ppl say yes some ppl say no i never have when breaking in my offroad reds motors but thought I would ask about the smaller size motors

30% is pretty standard. Factory needle settings should run but I would fine tune it after you break it in.

Yea I was going to do that as I belive they come rich from the factory I've just read ppl open up and richen it up even more me myself have always just taken the motor out of the box and left it at factory settings and just rand 2 tanks on the box and then drive it around at quarter throttle half throttle and then full throttle never brokenan onroad motor in so ddidn't know if there was a different method
