Unless I was told wrong 43. anything doe's not apply to your homebuilt airplane UNLESS you are running a certified engine and then all FAR's,AD's and such apply.I think Mark L hit the nail on the head with the part about using good judgement and staying close to a safe landing spot for the first few hours.Why would you want to put on a fresh engine certified or not and go flying long distances.I've not seen to many engine put on airplanes that did not require a little adjusting here and there.But as far as your auto or experimental engine on your airplane the FAR's do not apply....
