Weber 40 IDF help, My usual guy had back surgery and can't help now Options

Hi everyone,
My 75 is ready to drive again. I fixed the oil leak from the main seal a couple of weeks ago and all is good.
As I continue to do the shake out of the car, since I'm on the tail end of the restoration, I've had one problem the entire time and I need to get it fixed now.
Cold or hot, as I'm driving there's a flat spot when I shift between gears. It bogs and then picks up again.
It's particularly noticeable from 1st to 2nd and 2nd to 3rd. Sometimes even when starting for a dead stop.
I know NOTHING about carbs but I'm willing to jump in.
Does anyone have any experience with these symptoms? Is there a write up on the world that I've missed?
Would anyone be willing to work for high end craft beer and good pizza (along with an hourly rate) (IMG:style_emoticons/default/smile.gif) I'm in north county inland San Diego (Valley Center)
Mike

From my experience with 44 idf's and a bluetooth 123 the flat spots could be tuned out in the tune mode on the phone app. I note what rpm range the hesitation starts and bump the advance up till the flat spot levels out. Note the amount of advance in the tune mode and then with engine off but ignition on reedit the curve that is loaded. Then write that curve as a new curve and load. If close to idle hesitates bump low rpm advance to 8-10. I don't know for a 40 idf and your displacement/elevation if a 115 main is too low but my 44's at sea level needs 140 mains your other jet values seem right.
