Make sure during cranking you get a bright blue spark that can jump at least a 1/4"

I just re-read the blog & see you don't have an ignition resistor. I'd source one from a local auto store & temporarily install it in the power line to the coil to see if it makes a difference.

If you start the lift & slightly raise the rpm to where the engine seems to lean out & you keep the rpm there for a few minutes does any part of the lp system start to look frosty?
