I thought about what the engine was doing and why it was rich/lean/rich/lean ect. Woke up at 3:30am with the solution! Couldn't start car because of the neighbors so had lots of coffee.

Here's what I did:

Fixed! Posting this so I can help the next guy that does an internet search. Here's what I did:

Started off with the idle screws out 1 1/2 turns, had a 500rpm blower surge when engine is hot.

Ended up with idle screws at 1/2 turn each, and closed primary throttle blades 1/4 turn. OPENED secondary throttle blades 1/4 turn.

Engine now idles at 1200rpm with maybe a 50rpm surge or less. No smoke, no miss. Drop it into gear and it idles smoothly at 1100rpm.
