Here is some advice that is worth what you are paying for it.

If you don't have a pin gauge set, get one. Worth every penny.

Then pull the carb apart and pin gauge every single hole in the metering blocks. Then write it down.

I just did a gas carb and it had some holes that were absolutely wrong. Dead wrong. So I called Holley to make sure I wasn't nuts, and the answer from them was just as bad.

You may not have any issues, but you need to verify that stuff.
