I have a 1972 silver shadow LRA12701
Two questions needed to be answered.
What is the purpose of the Throttle Stop Vacuum Actuator? Mine is disconnected and the Vacuum retard tap has apparently been removed.The Vacuum retard line runs directly to the distributor and the T line that would normally run to the retard tap is plugged.
I noticed the "A" float chamber vent hose is disconnected from the Fuel Receiver and Float Vent Valve Chamber. When I connected it I experienced fuel starvation during acceleration higher than idle (700 RPM).When I disconnect it the acceleration returns to normal. The "B" float chamber vent line is properly connected.
In both cases my Motor seems to run OK but I like to have things as they should be!
