Please Read Full description.

Offered for your consideration is a OS Max 61 RF ABC “Hanno Special” engine. Model number 17804. Serial #0481.

First and foremost…. The original instructions - paperwork is not with the engine due to an unfortunate incident. I have included printed copies of the main instructions, parts breakdown and pipe setup.

Box has self wear as can be seen in the photos. Lower box has the corners split on one side as the box construction is basically held together by one big piece of tape from the factory.

Engine itself has never been mounted, fueled or fired. Everything moves freely as a new unrun engine should. All tools, head shims, needle and spare drive washer key are present and sealed as the day they left the O.S. factory.

Included with the sale is the factory O.S. header with mounting screws. The header was briefly mounted for display purposes so there is witness marks on the mounting flange. Header has never been run on an engine and has not been modified in any way shape or form.

Engine will be carefully boxed to ensure you get it exactly as pictured.
