Re: holley 1bbl carb trouble

[Matt Haas <mhaas@xxxxxxx>]

What you're describing is the power valve. It needs to be free with no 
vacuum applied. If it isn't, the car runs poorly. If it isn't working 
correctly, it will also hurt gas mileage, run over your dog, and steal your 
favorite CD (leaving the case behind).

Hopefully, you didn't hurt anything. You need to pull it out and check the 
rod to make sure that it doesn't have a grove in it. If it does, you'll 
need at least the rod and maybe a metering block if it was damaged (you'll 
also have to pull the metering block to check it but only do that if the 
rod is damaged). If you need parts, you'll soon learn that they're hard to 
come by. I may have an extra metering block and rod laying about (they're 
very grungy, the car the carburetor came off of sat in out with the hood 
open and no air cleaner for about 10 years). Let me know if you need them.
