OS FT 120 Gemini early version final run

Hello, my dear visitors and subscribers ! This part is dedicated for the final tuning and checking the idle speed of an O.S. FT 120 early Gemini flat twin engine, also, with the oversized 20x8 prop, which was installed only for testing, how the increased flywheel momentum can influence the idle speed. Definitely, much better to watch this video, than to try to explain its content. I can tell you, that its content is really interesting. Thank you for watching, and have a nice day !
