He was very tired today and none of them like pictures. ;)

So status, we figured out how to hot wire the car since we don't have an engine bay harness currently @SteveJ :)

We have spark and we have fuel but we couldn't get it to fire. Even with Ether...

We have good compression and we have the dizzy on the car on the compression stroke. Although the timing isn't set yet. But rotating it while cranking, we didn't get anything. No bump, no belch, no nothing...

Valve adjustment was done recently

My only idea at this point is that we flooded the engine with all the cranking time to sort the spark and distributors. Any other ideas??

I don't know if this is accurate, but for the L20, this site says the distributor orientation is different than what I would expect.

Thanks for that.

We set the plug #1 position by TDC and the rotor position. So we ended up with that L20 positioning through our methodology by accident
