Hello; Can that engine be mounted any way but upright? Will gravity interfere with OS' much publicized oiling system? I think so. So all you potential FSa 72 owners really want an engine that can only be mounted upright? Or are OS hoping no one will notice this little oversight? Why has no one thought of that yet?
Do you have a problem with an inverted installation. Do you have any details you'd like to share? The manuals for the currently available Alpha series do not warn against inverted mounting. I have my FS-52 with the same oiling modifications mounted sideways and didn't see any issues. There have been a couple Alpha series on the marketplace.
