I have not seen anyone mention it specifically, but if this IS an '83 550L, it should have the BSW two-barrel carbs.
Procedures and o-rings are just a bit different on these.
chrisptip, concerning your "third and kind of least important problem", assuming the carburetion and ignition are in-spec, the most-common cause of hard cold starting is VALVE ADJUSTMENT. Specifically, they are probably a bit tight. Your engine is a 16-valve, so not shims are necessary, but you have more valves to adjust. Since you have the option of setting exact clearances (shims have to go in rather broad steps), shoot for mid-range to maximum clearances.
