"Snigger, Snigger"Sorry couldn't help myself. I'll write out "I shouldn't snigger in class" 50 times as a punishment.
If the tickover screw when screwed all the way in still has a gap to the lever it adjustes you definately have the slides not right
It's exactly what a float chamber is for, to break the head pressure ( no sniggering at the back there, oddjob and Julie) and provide a reasonably constant fuel weight for the carb's vacuum to work on, which in turn gives you a chance of linear jetting response. If it didn't do this then as the fuel tank volume varied then so would the jetting and the float height would be absolutely meaningless.
Take a few photos, we may be able to spot the problem.
There's a mk1 lives near me, they look modern even now and very crisp design. We ran an 86yr Audi 5 cylinder some time ago a close relative in engine and fuel injection.I don't think there's any mysteries in the bike carbs, just a bit of time and careful setup and they're not much trouble when up and running. You can't be far from getting them sorted I think.
