It does not have an inbuilt fuel tank; I am in preparing to sell the engine. I think it looks like a .049 size motor.

Many thanks in advance.

Regards,
Martin

Yeah, it’s a late model product engine as found in many Cox Ready To Fly airplanes. Nothing special about it, probably out of the PT-19 trainer as that is the most prolific one produced. Don’t expect much for it.

Yeah it looks to have a “left-hand” snap starter on it. Other than the orientation of the spring, LH cams were usually black in color while the standard RH cake were normally gray. Older non-hex “snap starter” cams were usually red.

These product engines sometimes came with brass driveplates that I believe were designed to reduce wear between the crankcase and driveplate when used in pusher applications. Engines with brass driveplates were included on RTF models as well.

That needle valve could be a normal short needle with its plastic cap missing.

It’s hard to say what you’ll get for a product engine like that. On eBay, one day one will sell for only $8 and the next day you’ll see one sell for $35.

Welcome to the forum!

Hi, Martin. WELCOME!!
I'm pretty sure this is what you have.

I have an old plane with that engine, this one.

Also, davidll1984 is 100% correct. This particular engine uses the old style "circlip" reed retainer. Soon after, Cox changed
to the plastic flanged retainer.
