Holley Factory Refurbished Carburetors

Yep I've bought 3 of them. Just recently purchased a 850 brawler that arrived yesterday. The only signs of use is where the throttle cable was mounted and marks on the throttle plate when it was mounted. I bought a 950 quick fuel last month that was supposedly refurbished and it looks completely new. Also a holley 650 hp that looked like it was never used.
