Could be crap in the needle/seat.

Rich idle can be lack of timing and cranking up the idle on the carb to get it to idle.

What's your initial timing?
warmed it up and checked timing. 4 degrees on the nose at temperature. I believe idle was around 550-600 IIRC. And that matched up with the specs i found.

Also, if that fails, check your vacuum lines, especially your PCV.
I am a carb newb. no idea how to check the float level with the carb installed. vacuum lines all check out good.

Air cleaner off would be nice.

Slight chance you got a bad batch of gas too.
