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?

Last year I purchased a 1975 2.0 that had been removed intact, FI and all.

I never started the engine. Over the winter I built it to a 2056 using Ian Karr’s videos among many other resources. Check, double check, triple check, etc. I have rebuilt many engines over the last fifty years; this is my first Type 4.

Block: Refreshed 2.0 oem heads, new 96mm x 71 mm P&Cs, new SCAT C25 cam, CR 8.5:1

Fuel: New dual IDF 40’s (set up IAW Weber instructions), Edlebrock fuel pump #17301 38GPH @ 4-7 PSI,

Ignition: BERU ZS 172 blue coil @ 3.3 ohms, 123/TUNE+ 4-R-V-POR distributor installed according to the instructions (called 123 and they walked me through the installation and basic set up). Spark is white jumps ½ inch. I am not really happy with the spark, would a 1.5 ohm be better?

Timing: I have tried several curves, cranking rpm increases with 10* @ 500 to 28* @ 3000, it “chuffs” but won’t “fire off” past cranking speed.
