Hey gang.
I need some help figuring out what Holley I have here. I've gotten the all the numbers that are stamped on the thing and the closest I could find was a 580 that was sold on the 66-67 Corvettes. But when I got the rebuild kit for that carb, it turned out it wasn't for a matching carb. If any of you guys could point me in the right direction so I can finally get this thing tuned. If I slowly accelerate, it is fine, but it I get on it, it falls on its face. I'm not sure if I'm running lean or rich or whatever. Anyway, before I digress any further....

If any of you guys could tell me which adjustment screw is for the idle and which one is for the power circuit.

It looks like a holley 4160
Upgraded with a quick change vacuum secondary spring housing
and 4 corner idle screws
it'a a single pumper
too bad the choke plate housing has been removed, all the info you nedd would have been located there

Yep, pretty sure it's a 4150. It's got the 2 metering blocks.
