My question is: Have I terminally screwed something up? Should this happen?
What
do experienced roadster owners do in this case?

John,
You are talking about SU's, right? There are four screws that hold the
vacuum chamber on the top of the carb. If you loosen these up and then get
the piston positioned so it rises and falls smoothly before tightening the
screws, that might take care of it. If you have bent the needle on the bottom
of the piston it won't seat into the jet right and you'll have to replace the
needle.
