Need some help identifying an engine

I would post a picture but my browser is giving me fits with a time out error. Anyway, I acquired an engine that I can’t identify. Roughly cast case with a faint 1.5 on one side so I assume it is a .09. On the other side there is what appears to be a “J” with a dot on top of it. Cylinder looks like a Cox, black and with two exhaust ports. Head is aluminum with four slot screws holding it in place. Standard short glow plug. Venturi is black plastic and the spray bar assembly is like a super tigre as it does not go through the center but is on the outside of the venturi. Back of the case is also like a Cox as is screws in and has two slots for a flat wrench to sit in. From this anyone have an idea as to what it is?

Thanks!

Sounds like a Cipolla Jr. Later versions have larger cooling fins but my old one has the cylinder sorta like a Cox.

Edit: Forgot to mention, it runs well.

That's it! With the exception that the fins on mine are black - like a Cox and only the head is aluminum. Thanks!

I just updated my previous post. Sorry I didn't include pics before...just figured out how to. Had to turn off NIS to load them. Probably something about the hand-shaking process.

You fellows hit it - the Cipolla Jr (Cipolla is onion in Italian).
Mine is the RC version.
Weight = 90 gm
Bore = 12.55 mm
Stroke = 12 mm
17,000 RPM with a 7-3 1/2 prop

Yep! Mine is just like the picture George posted.

Thanks!
