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

[mmichalik]

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

Drilling new progression holes is a last resort and not for the home mechanic unless you have a mill to put them in a precise location in each barrel.

Spanish version Weber 45 DCOE's of the mid 2000's were notorious for this particular progression problem and the only solution was to drill an extra progression hole exactly like the original Italian 45's.

You might Google for pictures of 40IDF progression holes in an original Italian version and compare to your carbs.

There is no need to drill anything on IDF’s to get them tuned for a 914.
