Gas engine ID needed

Hi all,



I recently acquired an older 1/3 scale (Bob Nelitz) plans built Cub and could use some help trying to ID the engine. The engine appears fully intact (other than a good cleaning) I'm mainly interested in any available specs, manuals, etc.



I have posted some photos here:

Weight = approx 4lbs minus the muffler Length = 5.25" (front to rear) Height = 6" (not including plug) Width = 5" (includes carb)



Markings on cylinder "44 ZN 18"



It has a 6 bolt prop mount as shown in the photos, and has a 23 x 10 wood prop. To me, it looks similar to the J&A Engineering line of gas engines. See

Thanks for any help, Alan Harriman

It looks like it might be a Air Hobbies 3.2 (sachs cylinder & piston). Not absolutely positive though.

Nah, he paints his RED. Looks like an old Brisson with the sliding ring for spark advance. I don't recall if J&A did that or not.

Thanks for the replies. It looks like 3.2 may be right. I was able to measure the bore and stroke via the exhaust port and spark plug openings.

Diam = 1.75" Stroke = 1.375

Or approx 3.3 C.I. displacement? (or approx 52cc) Anyway, should be enough info to compare to similar engines for specs, etc.
