Founfd out ny problem with my 1982 2 hp Carb.... Top needle..(slow speed) has stripped threads inside the carb body thus messing up the whole carb. I found a 1974 2hp that appears to be the same carb as mine. I can only tell by pictures of it not physically seeing it. Does anyone know if these 2 carbureators are interchangeable? They do appear to be identical but like I said its from a Pic only. This would sure save a huge headache and money for a brand new one.
