I have a like new Holley 2-304 1 barrel econo mizer carb. Been in dry storage for at least thirty years. All the numbers are in the pictures, has the later style throttle cable hook up. 66? And up?... Selling as a mint core but would have no issues bolting it up and trying it as is. Asking $225.00 shipped in a priority mail box. I would use the original box for padding.
