I'm installing a 123ignition in a customer's 914-6 (conversion) and it's really kicking my butt. It's a 2.7 with PMO's, and as you probably know, distributor access is a PITA in a 914-6. Cutting an access hole in the firewall isn't an option.
I've never had this much trouble installing a distributor. I've done at least half a dozen distributor installs in a 914-6, a few 911's, and numerous 914-4's. I've confirmed TDC#1 with a scope in #1 (piston up, valves closed), and installed the distributor per the exceptionally generic instructions that came with the distributor. I've moved the distributor in roughly 1mm increments both directions about 20* and I can't get the engine to run. Some loud pops and bangs, but that's it. Any experienced advice would be appreciated! I like the concept of the 123ignition unit, but there's a few things about it that could stand improvement. The clips for the distributor cap are very flimsy for a new distributor in this price range and fit poorly. There were problems with the spring loaded center terminal of the cap right out of the box. There's no specific instructions for this engine. The US dealer, while a nice guy and good to return calls is not a mechanic and slim on tech support. It seems to me the problem is indexing the LED with the shutter while getting the rotor at #1 with the cap in the right orientation. I didn't think it would be this hard. Customer purchased the distributor on my recommendation, so I'm compelled to get it going. I've never had a car I couldn't get going, so this is frustrating. |

If you have it at TDC the little green light should be seen, then follow the instructions but it says rotate left i believe(advnace) until it goes out, then back until it comes back on and it should fire up, then set the timing adjst accordingly. right now i have my/4 set at just a bit more advance than factory, 30 degrees i think, and it fires right up first crank.

What dr.phil said. I just put one on my 4 and I had to stab it a couple times to get into a position where the led was visible at tdc so I could do the two other steps...in the end it was simple but those instructions mean you are flying blind till you get it.
