Trying to dial in my QFT 750

I have the same carb and have worked it out for the most part, first off, have you read this?

That power valve calibration sounds rich, 12.8:1 sounds more like it, it comes down to what your engine pulls best at. Idle A/F ratio is the same, wherever it want's to be smoothest at.

Have you bought a box of brass set screws? 6-32 8-32 and 10-24? 81-60 drill index with a pin vice? This way you can calibrate inexpensively.

If you haven't, do that first.

I'd start here, if you need help I can guide you. Start with the stock holley calibration from the 60's, go from there.

I had to dial back my idle feed quite a bit, pretty much EVERYTHING including airbleeds quite a bit. These carbs are setup for healthy big blocks as far as I'm concerned. Rich as hell!!!

I forgot that you are running the same carb. I've read the LS1 article and got into the Yellowbullet one, but thought that was a little to advanced for what I needed so I stopped, but I can continue. I was on page 3 of that one.

I was thinking that I need to increase my PV to a 7.5 and downsize my main jets.

For the idle air should I increase it for maximum vacuum or just see where it runs the smoothest at?

No I have not bought the set screws, drill index or pin vises yet? Like I said I thought that was to advanced for what I needed, but I most certainly can.

Thanks for the offer to help set up it up. When I get the stuff I'll get back to you.
