Hello All,

I am considering buying a barn find Luscombe B which has an Lycombing 0-145 engine. I know nothing about this engine. Can I get some insight on the cost to overhaul, who does it, are there still parts readily available? Are there exhaust parts and mag parts out there? I noticed that on one cylinder the two spark plugs are much larger than all the others, is this standard for the engine or perhaps it is a repair? What other aircraft flew with this engine? thanks so much.
