123Ignition Static Timing, Engine will not start Options

[SteveNMaine]

I just setup my carbureted 2056 with 123Ignition distributor and cannot get it started.

Basics: Compression is good, new dual carbs and there is spark.

I have read several methods of setting static timing,

Method 1: 123 manual says set timing marks at 0 TDC and turn distributor till light turns green, I did that, no Joy.

Method 2: Set timing marks at 7.5 BTDC and turn distributor till light turns green, I did that, it sounded more like it wanted to start but no joy.

Should I continue to advance the timing?

So, the next puzzle is this; when the 123 is setup according to the installation instructions, the engine will not start.

Ed at 123 suggested advancing the timing manually and the engine did start and now it idles at 7.5* @ 900 RPM and runs smoothly. However, the TDC green alignment light in the dizzy is now at the opposite end of the alignment slot where it comes on at 0* TDC and is turned off.

The dizzy now has no idea where TDC is and using the app to set a curve relies on that setting is right?

As long as the app is giving you what you see with the light I wouldn't worry about it. (truly set and forget in my mind).

Awesome to hear it is idling where it is supposed to be.
