need help with a power valve replacement
can someone explain to me how to get to the power valve? I took out the four main bolts that hold the bowl in place, but can't see how to get the plate that holds the power valve off. It's a Holley two barrell on my 1959 styleside with a 292.
Thanks for your help

Howdy,
well it is difficult to tell without know exactly which carb you have.
Go HERE for an exploded view of a Holley 2300 series 2 bbl carb. The power valve is #45 in the illustration.
Here's a 2010 series too...
If that's not the one you have you can probably search around for it on the Holley site.
Regards,
Rick

metering body
Thanks Rick,
the exploded view is great! I do have a 2300 series. I'm probably missing something very obvious, but when I take the fuel bowl assembly off the front, what is holding the metering body on? I'm I approaching this wrong? I'm trying to get to the power valve from the front, do I need to take the carb off? This is my first venture into a carburator so I'm flying blind. Wanted to get this done today and local auto parts store is closed today so I can't get a book on Holleys.
Thanks again for your help

most likely the gasket.... they get 'stuck' to the surfaces..
