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...

If it is like mine....it is 21.2 cc. Should say K3W on it if recall? Sears sold them also. Not mutch power on gas. Could be reworked into a more powerfull glow engine and lot less weight. Capt,n

Bob,
Based on the 32x32mm bore and stroke it is a 26cc engine. Much better then 21cc.

I'm not familiar with this model, but generally the Kioritz engines make some of the best conversions. Good power, low weight, high quality engines.

yeah, it looks like a quality unit, not sure how great of a conversion it would make coil wise, and with the plug up front in the way of the prop, but for what I made it fit it should be ok, as long as it can move someone around... I did give it 4:1 reduction with chain drive and a 10" tire which should put it at a top speed of 20ish so I think it'll work.

the 1.25x1.25 was a rough measurement but looked pretty close

now I just need to go get a diaphram or two, seems as all the carb's I have have worn out diaphrams which isn't helping anything... luckily it's a walbro so it should be cheap and easy to find
