Holley 2245 hesitation, missing power valve, no plug

[Dirtbag666]

So I bought a 1977 Dodge B200 van for nothing and drove it from 1600 miles. It has a 5.9 360. The only problem I've run into is it doesn't really wanna start in the mornings no matter what temp. I gotta my pump on the gas a bunch and leave my foot the pedal for a couple minutes after it starts. I'm still making some adjustments to the manual choke which has helped a bit with that.

It runs fine after that.

But there is some hesitation from a stop, going into the low rpm range. It runs fine in the mid and higher rpm ranges. It gets a little better after it's been driven for a long time.

So I popped the carb off to clean it and opened it up to find no power valve. It has 2 main metering jets that are both .642 (close limit jet?). Both main jets turned all the way down.

It has the power valve piston assembly of a 2245 but no power valve to mate with. Could this be the problem I'm having with hesitation?
Also what's up with the jets being turned all the way down? Shouldn't they be adjusted in some way?
I have the Mopar manual for that year and it lists carb numbers
R-6764A
R-6765A

No mention of R-7871. Maybe this carb was originally from a truck and not a van?

When you say"jets" are you referring to idle mixture screws? The main jets should be screwed tightly into the floor of the float bowl. Is the power valve cavity empty? Is it threaded to accept a power valve? Are the connecting passages from the PV cavity to the main jet cavities present? It may be a cobbled up carburetor.

No answer? Must have got it fixed.
