What Is This???
 

Hi,

Recently acquired a strange engine. The cylinder looks just like my Kioritz 16cc only with larger fins. Intake port, exhaust port, and cylinder bolt holes all look the same. But it has this weird crankcase and shaft. It had a large aluminum plate bolted to the housing that held a bearing. Can't be run without the plate/bearing, as that helped support the crank. Anyone know what it is and what size? I'm wondering if I could use the cylinder and piston as a "big bore kit" for my 16cc. It sure looks exactly like my 16cc only with larger fins.

Help?

Thanks AV8TOR

Good eve, I wonder if I could ask a couple of ?'s. A couple things jumped out at me as I was reading through all of the replys. I noticed that not once did anyone talk about a "thrust washer" to prevent the prop from "pulling" the crank out of the front of the crankcase. Is this not a possibility? I am completely green to this but that is what I heard years back. Secondly, how is the prop fastened to the crankshaft? Is it a good thing if an engine has electronic ignition? I had a stihl 70 cc chainsaw that I would like to try something with given to me. lastly, and thank you for bearing with all my questions, how would a person know what size a plane to put a given engine onto?
Thanks for your time. I look foreward to learning from all of you!!

Cylinder looks just like a McCulloch Eager Beaver...
If it has a Walbro carb the numbers can be cross referenced to tell what it is....
