holley carb help

I got a 4779-2 750 holleydp.Do these carbs come with only one powervalve or did i get gyped> thanks Paul

As best as I can remember it should only have the one in the front. Typically one in the back bowl gets uncovered upon launch. What are your jet sizes front and rear. Should be quite a few numbers larger in the rear if no P/V. It's been a while since I've fooled with any 4150 carbs.

4779-2, 70 jets in the primary w/6-1/5 power valve. 80s in the secondary and no power valve.

that sounds ok,what kinda trouble you haven with it?

no problem with it just thought it had 2 power valves and that i got screwed.Just needs a good cleaning and new gaskets.70 front 80 rear with a 6.5 power valve.thanks guys for the help.
