yesterday run in/broke in the engine bolted it on the model.. using 2/12" plastic spinner.. hand flick more than a dosen times.. at last it ran.. I had to run it rich for full tank.. no tachometer used yet.. I could feel the power already with 16X5 wooden prop.. looks like the homemade manifold is gonna work alright... tomorrow can tune the engine to optimum RPM and hope have gut to maiden the plane..
