I'm ready to mount my OS 46 in my phoenix decathalon. The manual shows 2 degrees down and right thrust. Does anyone know if these angles are built into the fire wall? Or will I need to adjust? The mannual doens't say. What is the best way to measure the thurst angles? Also, ?? for the high speed needle adjustment. What do recommend for an extention? Lanyard or music wire? Cause there is no way I'll be able to reach it with the cowl in place. The engine is mounted 45 degrees to the right side of the plane, that is to say 45 degrees from inverted to the right.
