That's usually a blown power valve, or most likely, if the rear block has a provision for a power valve and you are running a plug (or even the power valve) that plug (or power valve) can be hitting the boss in the power valve well in the main body.
Look very close at the boss in there. Take the gasket off the metering block and with the PV or plug installed make damn sure nothing is hitting anything.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

One of mine did that, and it turned out I had somehow warped the metering block.
I hope yours is a cheaper fix.

I hope yours is a cheaper fix. Yep. That happens too. Also, the main body can warp and drive you nuts. Before I had a mill, I used a roughing file and filed the main body flat. When the metering block is warped...that's a horse of a different feather. At that point, I'm looking at a new carb. With billet blocks and base plate and an aluminum main body that doesn't seem to warp like that Holley zinc mix or whatever it is.
