Can't get the idle right

[JOES31]

No upgraded cam or high compression head. I also have two fuel filters. One in the sediment bowl and an inline after the bowl. Gas tank was flushed out before I started it after the long storage so I know it's not contaminated fuel. Would an idle jet problem cause this? They are new flow tested jets. Maybe too small? Running out of ideas other than this is the way these cars run.
