When I replaced the upper chain rails in the 117 a few weeks ago, I removed the distributor to gain access to the power steering pump bolts. I indexed it when I removed it, and it all wen back together just fine and runs well.

My question is, is there any adjustment that is made by turning the duistributior? I thought the electronic ignition determined when the spark was delivered. Is there any signifigance to how the distribitor is positioned, other than to be "close enough" so that the rotor is still in the range of the pickup for each of the 8 wires when the coil firers? I really like distribitorless.

cheers
