does the temperature outside matter at all when u use ur engine or break it in like i am soon to do?

like should it be 0 C, 5 C or 10 C or it doesn't matter.

does it extend ur engine if u do it a certain temp.

glad to hear what u all have to say and if u have any tips or tricks to help make ur engine last and run, i would be glad to hear em

i just bought a OS engine, the .18 CV-R with rotary carb

thanks
