Hi all,
I'm a 17 year old doing up a 1982 280ZX, which I bought a few months ago, not running when I bought it. At the current time it idles fine, and I can rev it up. I've set the timing to 8 degrees BTDC, but I'm having trouble working out how my distributor advances the timing. I understand how mechanical advance works with weights and springs, and I've read the FSM. The FSM says that the electronic module on the side of the distributor should have 2 plugs, each with two wires (ie. four wires total). Mine only has 1 plug, the one that connects to the coil. The distributor has weights and a governor built in, but the grooves in the shaft assembly don't appear long enough to provide any mechanical advance. So it looks to me like the distributor doesn't do mechanical advance, but doesn't have the wiring for the ECU to control the timing. I've triple-checked the wiring loom, and can't even find a plug for the supposed second connector to the distributor. It looks to me like the engine is meant to have mechanical advance in the distributor.
Do I have the wrong distributor? Am I missing something?
