I can't balance my carbs. Picture below:

1-2 is out of balance with 3-4. Anti clockwise on the centre screw should help with that, but it doesn't. I've screwed it right out to where the screw is wobbling as it's lose in the seat. Turning it the other way Makes 1-2 bog and ultimately the engine stall.
I can't get 3-4 to shift at all, they're up at the top of the gauge always. They respond normally to throttle, coming down before easing back up. Choke brings 3-4 down a bit, and 1-2 isn't changed much. They looked roughly equal on the eye test before I put them in, just open on the tickover.
I can't get the tickover down below 2.5, I think I'm right out on the tickover adjuster too.
Any suggestions before I pull the carbs out and have a look to see whats up? Things to look at when I do? Bit of crap stuck under one of the butterflys I see as a maybe, can't think of anything else.
The background: carbs are a different set to what was in a week ago, cleaned. I balanced the old carbs only 3 weeks ago, no issues. I've got new spark plugs in. New carb inlet rubbers. Exhaust headers reseated. New coolant, new oil. Coolant rubbers and rad replaced.
Thanks if you can help, I'm having a bit of a mare over here, it never seems to end.
