Dear OP
I am always amazed at six pak threads.
Some bad advice and no one discusses how to baseline a six pak.
It is a fundamental procedure that is well documented and tested.
It is stickied on the lift off hood playground forum and has been posted here many times.
It works, I do not know why no one suggests the proper info.
You have to baseline the set up!

In the working world I provide technical support on very complex technology so I might have a clue about troubleshooting complex systems, writing procedures and testing them.

PM sogtx if you want offline help. He is very six pak literate.

Just a few more comments and I will leave you in the hands of the experts...

I do not understand why people will not give you the proper help when they have the same information as many others.

If you read the guide you will learn:
A properly tuned six pak starts easily hot or cold.
The transition to the secondaries should be seamless.
If there is a bog - the bog is a LEAN bog.
The fuel levels are different that what has been suggested.
Use the carter street pump and 195 degree thermostat.

Good luck
