I applaud your effort and like the oiling spigot. That should work very well and I'm likely to steal the idea. I am a bit of a novice on the these motors but not to the topic of oiling a myriad of industrial chain and gear drive systems. I think as long as you have a decent flow of oil onto the large gear, it will make its way out to the gear teeth and then around to the other gears in short order. And then around and around. It would essentially work as a flood lubricating system. Yeah, some gets flung off but chains and gears like this don't need a constant flow like a plain bearing on the crank does to maintain the fluid film.
