How thick are your washer on each throttle needle? I've just been through this on my 78 carbs with pods as well (with a lot of help from Houndog750 here on HC.com).
You're describing the same problem I had (have) with mine.
I've been shimming my needles one washer at the time and doing plug chops. I'm up at 1.25 mm with washers on each needle now and it's almost perfect. Another 0.25 will do it I think.

So my GUESS is that you need to shim your needles some more - and do plug chops to confirm.


Some people need a high five.
In the face.
With a chair.
