All timing were checked but on start the prop turns very slowly even with 45-50 pressure in system. Turning the prop by hand feels ok. If the pressure drops below 30 the prop does not turn. Any ideas..

I also do not like offering advice on something that I do not have complete information on. That said. The air distributor that controls when and how the high pressure air is injected into the cylinders is driven through the same drive shaft that I mentioned to you regarding the timing of the mags. If this air distributor is out of adjustment in any way, the engine will not turn correctly when you apply air. Let me be clear. I am not there. I do not see the specifics. I am not telling you anything is badly wrong. What I am saying is that it is slightly worrisome that the engine is not turning correctly when applying air after a prop strike since the accessory drive shaft, that can twist from a prop strike, controls the air distributor as well as the mags. Let me repeat ..... there is no cause for alarm at this point, and I am not saying the sky is falling. What I am saying is that it bothers me a tad. That's all. Let's let the experts chime in.
