Trouble with idle and warm starts

Willoughby ambient temp today was 70-75. Elevation is pretty close to sea level.

Checked PCV and looks okay. Shook it and it rattles. Checked vacuum lines from PCV to carb and brake booster to intake manifold. I replaced the brake booster line because it looked sketchy. I checked all other lines on or attached to the carb and they looked okay (removed and inspected for cracks).
After a little research I determined the carb is a Holley 2 barrel Model 2210.
Today I started the car and ran it for about 5 minutes. The car ran okay and idled high okay. I didn't try to kick it down to a low idle. I let it sit for a few minutes and tried a restart. No dice. Choke plate was completely vertical.
