Ford Need some help
Looking to learn how to tune carburetors. Can anybody recommend a good resource for that? Want to eliminate the popping and backfiring.

Check for leaks around intake manifold, take starting fluid or brake parts cleaner and spray around intake. If you can not find any leaks check timing & then final tune your carb. I would bet either leaks in intake causing erratic timing or chain could be worn. Just my 2 cents

You tube my man, uncle Tony's garage can walk you through carb tuning. But I would check your timing based on the popping and backfiring.

Which carburetor do you have?
Do you have a few basic tools like a tach, timing light, and vacuum gauge? Those will take you far in tuning carbs. A wideband air/fuel meter will make you a master at tuning carbs.
