thank you for taking the time to criticize my thread. i however never claimed to be an expert or "guru". i do not use Holley look-alike carburetors and therefor have never tried to tune one nor wanted to. i told him what i thought could be a possible problem and then clearly stated that i couldn't help. the fuel enrichment from the power valve passes fuel directly through the valve and into the metering block. also, why would you install a holley with a 65pv on an engine with a cam whose powerband starts at say 3000-4000rpm? the pv will stay open and cause a tuning nightmare. my objective with this thread was to further help someone who became lost after reading the sticky. it was not an attempt to "show off" my knowledge or to offend the sofakingdom guy. i guess you like to show off your wits which is why you couldn't send me a private message and i could edit any incorrect info in my thread.

No attack meant. I only hope to clear up what I feel I know to be correct and when I can. I am no guru either. I try to post only when I know my information is sound and will be helpful.

"why would you install a holley with a 65pv on an engine with a cam whose powerband starts at say 3000-4000rpm? the pv will stay open and cause a tuning nightmare."

Probably will stay open. But even at idle, no big deal. The main jet it not flowing so it won't have an effect. The IFR is the restriction to the idle circuit and much smaller than the jet. And honestly any cam that starts at 3-4000 is more than likely in a drag only ride that 9 times out of 10 is square jetted. For a street ride I prefer and set my PV rating as Sofa recommended. Try it, it works.

I just wanted to add that most advance timing lights do work with an msd box, all of the digital ones I have used work great.
I haven't tried any dial types lately, so I can't help there.
This is all useful info but remember just cuse it's on the net doesn't mean it is correct, or incorrect. However it someone is spending his own time to try and help others and admitted he isn't familiar with a carb that really is a billet parts collection and didn't mislead the guy, I think he deserves a thank you, but some small things are technically incorrect, but unless one is an engineer it is more about how to help the problem ....

after being fed up with both threads I talked to Holley themselves, since they are in the next town over, and got the info I needed.

For anyone else that needs this info like I did after screwing up the "setting" for the secondary throttle blades...

The email response from Holley said to back the screw off the secondary throttle blades until they completely close, then turn the screw in until it just barely contacts and then turn in 1 full turn. I called the tech line just to be sure and also got more info with it too. The tech on the phone said to turn the secondary throttle blade screw until you have made a square out of the transfer slot visible under the blades. I asked for the reasoning behind this so I had a better understanding behind the operation and he said that this is to improve throttle response in the low end, so it has enough air for idle without getting too far into the transfer slot in the primaries.

Could be possible the carb is not tightened evenly and causing binding in the throttle shafts as already mentioned since it is a new install and problem.

Have you adjusted the choke at all?

Check this out....

* Choke Adjustment Again, most of the factory Holley settings will probably work for your 4x4 just fine out-of-the-box, but if you want to tinker and fine-tune things keep reading. The fast idle speed is adjusted by using a 1/4-inch wrench on the screw below the choke housing. Turning the screw clockwise increases the rpm, while counterclockwise, of course, decreases rpm. Try for a final speed of about 1,500 rpm. By loosening the black plastic choke housing you can adjust the duration of the choke. If you want the choke to stay on longer, turn the housing counterclockwise. Turn it clockwise to have choke operation end sooner.

I know it is a truck avenger but still an avenger none the less.

If your idle is too high setting the rear speed screw as suggested by the Holey tech is not going to help you. Although his reasoning is valid.

As said before the choke is set properly. Idle is working properly now, I was posting that up since following that sticky screwed up the carb's settings. However, saying that does NOT mean that the info in that sticky is wrong, I just posted that info from Holley so that if necessary we could set the carbs back to "stock" and start over. The only info I found wrong was that direction in which to turn the screw to get the wanted result.
