First engine build question

wow, this is being made WAY more difficult than it needs to be, than it has to be, than it should be. It takes pages to discuss DCR/static, what's correct, altitude, longitude, full moon, on a Septober night! LOL.

IKR? All the forum geniuses have to come out to show how smart they are. Just measure what you have, and put it together. It will be fine.
