A new question I have now is mounting the engine inverted or upright in my Four Star 120. I'll have an open cowl for easy access, so I figured that mounting the engine inverted would be a prefered way because I would be able to adjust the high speed and low speed needles eaiser. Am I on the right track, or is there something else I should consider?
By the way, I really don't plan on doing a complete breakin on a test stand. I just want to run a couple tanks of fuel to get some initial adjustment on the carb and to help me get a little familar with a gas engine and what it will take to start it before i mount it on my plane. I still need to finish building my Four Star.
