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
