Just what the man said; treat them too nice and they'll never perform as well as if you abuse them a little from the start. Don't over do it but don't be afraid to twist that throttle and see what it can do. Avoid long downhill runs that can starve your engine of lubrication but these little engines respond well to a little hard running, even from day one. Use good quality oil at 24;1 moving down to 32:1 after a couple of gallons. Keep us informed.
