91 FX
 
I just purchased a 91 FX. I have not run it yet. After putting on a prop I tuned it over as if I was starting it by hand (without a glow pug attached). When the engine bounces back off the compression it has a ticking noise as if the connecting rod is tapping the inside of the crankcase. Is this ticking sound normal? My 46 FX makes no such noise.

RE: 91 FX
 
The 'ticking' noise you hear is most likely the ring tapping against the ports in the cylinder liner. It's common with large engines. You'd not likely hear a rod because the oil would cushion it.
