I love this kind of stuff. I would definitely not throw it out. If you don't think of something now you will later. (Yes, you can tell from my logic that my garage is full of "projects".)
i was kind of thinking the same thing as the bar stool go cart.
ive also been wanting a lathe for wood working. i have a couple of weed whacker engines and an electric motor lying around ive been tempted to create a lathe with... but my luck is id cut my hand off
I have a blender made from what amounts to the same engine... Mine's commercially made (tailgator), but very cool and would be easy to rig up from your motor.
never thought about that cause i could sure use a pump to get some water out of my front and back yards.... not sure id know the best way to get a pump running off of it though. *def dont have the parts laying around for that... i dont think atleast.
