I see a company is selling remanufactured and tested edlebrock marine carbs (E-1409) on ebay for $249.00 (600 CFM, eletric choke). Anyone have any personal expierence with a carb from these guys (National Carburetors)? Any other general opinions. See how it would cost me $60 just to get my quadrajunk choke working (with eletric conversion) and the fact it has been rebuilt in the 4 years I've owned it, and who knows how long before that (if ever, on a 20 year old boat) this is looking like an interesting option.
