I just purchased a 1977 280Z as a project for my son and I. We are new to the Z car world. The car runs pretty well considering it has been sitting for a few years and is drivable after getting a new set of tires. The car is stock with the exception of triple webers and some modification to the vacuum advance that I don't understand. We are in the process of putting together the priority list for this project which will probably take a few years. But, in the meantime I would like to make the car a bit more drivable. The immediate performance problem is that the engine "bogs" down when accelerating in 1st and second gear. The car doesn't stall out completely but seems to be starving for fuel. To compensate, you have to start out with at high rpms. The power loss is dangerous when pulling into traffic and especially dangerous for my son who is just learning how to drive a manual (so no, he is not driving the car alone or on a daily basis right now). Once you get the RPMs up, the car runs great. The car idles fine also. I know there are probably a 1000 things that could be contributing to this problem but I thought is would be worth a shot to get some initial feedback from those with some experience. My gut says that whatever was done to the distributor to modify or shut off the vacuum advance is the issue. Thanks in advance for your input!

Hi - I've replaced my stock 240Z distributor with an E10-80 from a 1980 280ZX. I've replaced the advance plate mechanism, magnet ring and now also need to replace the vacuum advance which bolts onto the outside of the dizzy. Does anyone know the correct part number for a *single-line* vacuum advance which will fit into this distributor form/fit/function? Note, the original 280ZX vacuum controller had 2 vacuum lines -- I think one was advance and the other for anti-backfire retardation -- but I only need a simple 1-line controller which has the correct mount hole location and arm length. Thanks in advance, Sean Gillen Arlington, Tx

Just lately,I had an issue with my 77 280 running excessivly rich.I figured out it was a bad fuel pressure regulator,and a stuck injector.I replaced FPG,and all the injectors,and now she runs well.While I was replacing these parts I noticed a green wire that was cut.It goes to what looks like some sort of sensor that is threaded into the side of the BCDD.I also started car and pulled vacuum hose going to vacuum advance unit from BCDD unit.Even when I revved engine to 4500 RPM,and then let off throttle suddenly,there was no sign of any kind of vacuum.Is there suppossed to be?Also I remember faintly something about VAC. ADV.not kicking in until 5th gear was engaged.Sound familiar to anyone?{Anyone know where the green wire might connect to?}
