This is anicevintage carburetor from a 1972 Piper Cherokee Cruiser with a Lycoming engine. It is a Marvel Shebler Aircraft, Model No. MA-45 2A, Part Number 10-5009, Serial number BC 15 5237, Casting Number 15589? It also has the aluminum air valve attached, as shown. This will need a rebuild, as it has been sitting in storage, mounted on the engine, for 30-40 years. The top butterfly does not open, as it is connected to the accelerator pump, which is not moving, or seized. The rubber gaskets/parts in old carb pumps tend to get hard and stuck. I am parting out this plane, more parts will be listed soon.Please ask questions if needed. Any white spots are camera flash reflections. Free Priority Mail shipping, U. S. addresses only, International shipping is not available..........The terms...I prefer payment within 2 days from end of sale. I pack very well, and do not charge anything extra as "add-ons". I either charge exact cost shipping, or a flat rate that usually costs you less than it takes for me to safely ship the item. Due to my geographic location, I will not ship Fed-Ex. I do not end sales early. Please ask questions if needed, I am usually very prompt in my answers. I want you to have a simple and worry free transaction, as I take pride in being a professional. I have been selling on for over 18 years now. I treat my customers as I would expect to be treated.
