OK... Couple things.
The pump jets are 50s and the Exhaust valves are 0s.
Chokes are 37s

To Gaz64's comment about info on this site... I agree and I have read every post available on the IDAs multiple times over the last few months.

To Gaz64 and Priobe... I was trying for an AFR of about 13 to get the best HP. Is this about right? Also, the idle circuit is rich because I was trying to get it to work with the 3/4 turn of the screw. But every time I would try, I would get popping out the exhaust on deceleration from a modest 2500rpm. If I would go 1 1/2 turn out the popping would clear up. This was true with 65 idle jets. So my thought was to go to a 70 idle jet and decrease to 3/4 turn at idle. This did not work. 3/4 turn with a 70 still puts me at 16 - 17 AFR at idle and anything below 1 turn still produces popping.

The F16 tube was recommended by Chuck at Inglese. Per what I have found in the weber books, this tubes claim to fame is to bring the main circuit transition to lower in the rpm range. What would the advantage of the F11s be?

Thank you in advance for the help.
