318 Running Rough / Backfiring

I would not be surprised if the carb is not set up correctly. The PCV valve is a 4343581.

I have tried tuning the carb myself but it's my first time trying that.

I have the Edelbrock AVS 650cfm carb 1806, I also have the 1840 tuning kit that has additional sizes for metering rods, jets, and metering rod springs.

Currently running .092 primary and .098 secondary jets. Also .065x.047 metering rods and the blue springs I believe.

Might be able to double check tomorrow along with idle vacuum and all that.
