ok, I've had this Kioritz engine for a while and I don't know what the heck it is. it's older (early 90's at the newest I'd guess), dual pinned rings, 1.25" bore, 1.25" stroke, spark plug is forward facing and is nearly parallel with the crankshaft, magneto and pullstart are on the back, it's from a weedie that had a clutch with like a 17mm hex drive, the case splits at the center (4 screws holding it together), 4 screws holding the jug on, domed piston face

any ideas? I've searched and looked for pictures and none of the Kioritz engines I've seen looked like this one, I'll attempt to get a pic or two later...

this is going on a scooter, since that's what I had at the time I decided to make the scooter, with the rear starter and stuff it's probably not the best conversion anyway...
