Haven't touched it in a while, I thought about trying to keep it vertical shaft, but the only way to keep it like that is either with a transaxle from a lawn tractor, or a 90° gearbox.

So how to modify the oiling system without putting an oil flinger on the rod cap and unbalancing it...

Plus I need to clean up the intake and exhaust ports (maybe), get a different carb, and find something to put it in... Among other things. Like a tiny turbo.
