Jeff, I did. After fiddling with my Bing Carb with two tuning kits
(needles) and various inlet designs to get my EGTs to even out, I could
never get my idle to run smooth under 900 rpm (I have the Jab 2200
serial #852 with 180 hours). I finally drilled out the idle air inlet
per the JSB and now after fiddling with idle jets and idle adjustments,
I can't get a decent idle under 950 RPM.
I don't recommend it.

I did the original tuning change 2004 and drilled out the jet. It works fine.

A lot of folks have gone about their Bing Carb issues by changing out the needles,
etc. What I've found is that the air intake system will make a huge swing
on performance, EGTs and can fix things just as well.
While I think this is a long shot, it only takes a few minutes to try and would
eliminate it from the possible problem list:
Block up your air intake port on the cowl and then remove the air-intake tubing
from the carb so it draws air from inside the cowl and then finally try starting
cold. If it works, then you have an air intake system issue.
As they say, it is either fuel, air, or spark :)
