finally had a chance to start the Stearman , the engine is unbelievable , started second flip and you barely have to move the prop to restart ,hardly even a flip .Even after 1 hr it just starts first flip . crazy . best running engine I have ever seen . I will put a couple of tanks through it ,set the valves and hopefully next weekend I can do the maiden ..I never let a new engine idle because oil distribution is poor at idle with premix four cycles . After a few tanks I will take a vid of it ticking over.
