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?

If it ran well before you pulled the distributor, then the distributor drive is probably indexed properly. I’ve never had the drive gear come out with the distributor.

When in doubt take off the valve cover to make sure you’re on TDC #1, you could be 180* out, remember it takes two revolutions of the crankshaft to complete the firing order. Next make sure the distributor drive is properly installed per the workshop manual. Then make sure the rotor and cap are on #1.

123 distributors are installed at zero degrees on TDC #1. The distributor handles all the advance.
