Al, I'm just finishing my Stearman. All I have left to do is start the break-in on the engine. I'm using the BCMA 26 for power........glad to hear you have some experience with this engine. Could you tell me what size battery you are using to power the electronic ignition. And, I think you said something about a 18-6 prop?........Doesn't Adam recommend a 16-8 prop? Anyway, thats what I'm going to start with.......I'm going to start a fire in the shop today and see if I can get the 26 to run.......if successful, I plan to run a couple of gallons of gas through it before I bolt it on the plane......never been a fan of breaking in the engine on the plane.
Thanks
