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? |

The dizzy now has no idea where TDC is and using the app to set a curve relies on that setting is right? I have a feeling you installed the dizzy 180* out. Pretty common. If this is the case just flop the plug wires to match it 180 out on the Dizzy end. My 914 ran this way for years, and the T4 engine in the bus I'm building also has the dizzy 180 out (but that ones not on me). Whoever built the engine likely put the cam gear in backwards. The 123 does not care where it is pointing, so long as the leads are where it expects them to be. Zach |
