RE: 1973 350 slc
Be sure that the new ignition points have been set correctly (a dwell meter should be used rather than simply setting the gap). The fuel injection on this car is Bosch D-Jetronic. You may want to search the various forums using this term. It is a fairly basic system that relies on timing signals from trigger points in the bottom of the distributor (these can cause mis-firing on high mileage cars). Fuel mixture is determined by a manifold pressure sensor (mounted on the left side of the engine bay in the SLC, these can cause mixture problems) and coolant and air temperature sensors. Fuel pressure regulators maintain correct fuel rail pressure for the injectors. Contacts operated by the throttle spindle give fuel enrichment on acceleration (and at wide-open-throttle in the case of the 4.5 engine) and fuel cut-off on the overun (this unit must be correctly adjusted relative to the throttle position). The heart of the system is an analogue equivalent of an ECU (mounted above the passenger footwell in the SLC). With the symptoms yours has I would be checking for fuel starvation (fuel rail pressure) assuming that the ignition system (points etc.) that has recently been worked on is in order.
Regarding the seat back locks for the front seats on the SLC, they are vacuum operated. They should lock with the engine running and doors closed. Opening a door or pressing the black buttons either side of the rear seat (near ash trays) should unlock the front seat backs.
