I got a brand new street master air gap on Black Friday last year for $140 to my door. And I got on the Holley website and they have factory refurbished carburetors. I got a 750 street demon for I think about $225 brand new or factory refurbished... It actually had some junk in the float bowls when I went to set the floats like the instructions say to do and I told Holley and they just sent me a brand new carburetor...
They didn't have any carburetors factory refurbished so I put myself on a waiting list and it just took a couple weeks...
